A valve flow-directing vessel (42) comprising a sleeve (44) having a threaded installation portion (84) for connection to a receiving member, a plunger (46) movable within the sleeve (44) between a closed position and an opened position, and an orifice insert (48/50) fixedly attached to the sleeve (
A valve flow-directing vessel (42) comprising a sleeve (44) having a threaded installation portion (84) for connection to a receiving member, a plunger (46) movable within the sleeve (44) between a closed position and an opened position, and an orifice insert (48/50) fixedly attached to the sleeve (44). The orifice insert (48/50) defines an orifice (132) that is sealed when the plunger (46) is in the closed position and unsealed when the plunger (46) is in the opened position. The orifice (132) is the entrance to a passageway (130) having an exit (134) communicating with a delivery passage of the receiving member, and this exit (134) is positioned beyond the threaded installation portion (84) of the sleeve (44).

The invention claimed is: 1. A flow-directing vessel for installation into an interfacing cavity having a cylindrical wall with a threaded portion, a supply passage located below the threaded portion, and a delivery passage located below the threaded portion; the vessel comprising a sleeve, a plunger movable relative to the sleeve, a cup fixedly attached to the sleeve, and a capsule fixedly attached to the cup; the sleeve having a threaded portion for mating with the threaded wall of the interfacing cavity to connect the vessel to the interfacing cavity, the cup having a U-shape cross-section formed by radially spaced apart inner and outer walls, and an upper axial wall extending between and connecting the inner and outer walls, the upper axial wall including at least one opening, wherein the inner and outer walls and the upper axial wall define a chamber that opens downwardly for communication with the supply passage; the capsule comprising an orifice in communication with the at least one opening in the upper axial wall, an exit for communication with the delivery passage, and a passageway from the orifice to the exit; the plunger sealing and unsealing the orifice to thereby seal and unseal the passageway from the orifice to the exit such that when the passageway is unsealed, fluid from the supply passage can enter the chamber and pass through the at least one opening in the upper axial wall to the orifice and then through the orifice into the passageway to the exit. 2. A flow-directing vessel as set forth in claim 1, wherein the cup and the capsule are not formed in one piece with each other. 3. A flow-directing vessel as set forth in claim 2, wherein the cup is press-fit into the sleeve and wherein the capsule is press-fit into the cup. 4. A flow-directing vessel as set forth in claim 2, wherein the capsule is a one-piece body and the cup is one-piece body. 5. A flow-directing vessel as set forth in claim 4, wherein the cup and the capsule are not made of the same material and wherein the capsule is made of a durable corrosion-resistant material. 6. A flow-directing vessel as set forth in claim 1, wherein the cup surrounds the capsule. 7. A flow-directing vessel as set forth in claim 1 and a solenoid assembly controlling movement of the plunger. 8. A flow-directing vessel as set forth in claim 1, wherein a solenoid assembly mechanically biases the plunger to a closed position sealing the orifice and, when energized, moves to the plunger to an opened position unsealing the orifice. 9. A flow-directing vessel as set forth in claim 1 and a receiving member comprising an interfacing cavity; the interfacing cavity comprising a cylindrical wall with a threaded portion, a bottom wall structure below the threaded portion in the cylindrical wall, a supply passage situated in the bottom wall structure, and a delivery passage situated in the bottom wall structure; the sleeve's threaded portion engaging the threaded portion of the cylindrical wall of the interfacing cavity; and the chamber communicating with the supply passage and the exit communicating with the delivery passage. 10. A flow-directing vessel as set forth in claim 1 and a receiving member comprising an interfacing cavity; the interfacing cavity comprising a cylindrical wall with a threaded portion, a bottom wall structure below the threaded portion in the cylindrical wall, the bottom wall structure comprising a first bottom wall and a second bottom wall positioned at different heights relative to the cylindrical wall; the interfacing cavity having a supply passage situated in the first bottom wall and a delivery passage situated in the second bottom wall; the sleeve's threaded portion engaging the threaded portion of the cylindrical wall of the interfacing cavity; and the chamber communicating with the supply passage and the exit communicating with the delivery passage. 11. The flow-directing vessel of claim 1, wherein the cup is fixedly attached to the sleeve by engaging the outer wall of the cup to an inner wall surface of the sleeve, and the capsule is fixedly attached to the cup by engaging the inner wall of the cup to an outer wall surface of the capsule. 12. A flow-directing vessel as set forth in claim 1 the cup further comprising at least one rounded shoulder between the inner wall and the upper axial wall or between the outer wall and the upper axial wall. 13. A flow-directing vessel for installation into an interfacing cavity having a cylindrical wall with a threaded portion, a supply passage located below the threaded portion, and a delivery passage located below the threaded portion; the vessel comprising a sleeve, a plunger movable relative to the sleeve, a cup fixedly attached to the sleeve, and a capsule fixedly attached to the cup; the sleeve having a threaded portion for mating with the threaded wall of the interfacing cavity to connect the vessel to the receiving member, the cup having a U-shape cross-section formed by radially spaced apart inner and outer walls and an upper axial wall extending between and connecting the inner and outer walls, the upper axial wall including at least one opening, wherein the inner and outer walls and the upper axial wall define a chamber that opens downwardly for communication with the delivery passage; the capsule comprising an orifice for communication with the at least one opening in the upper axial wall, an entrance for communication with the supply passage, and a passageway from the entrance to the orifice; the plunger sealing and unsealing the orifice to thereby seal and unseal the passageway from the entrance to the orifice such that when the orifice is unsealed, fluid from the supply passage can enter the passageway through the entrance and pass through the orifice to the at least one opening in the upper axial wall and then into the chamber to the delivery passage. 14. A flow-directing vessel as set forth in claim 13, wherein the cup and the capsule are not formed in one piece with each other. 15. A flow-directing vessel as set forth in claim 14, wherein the cup is press-fit into the sleeve and wherein the capsule is press-fit into the cup. 16. A flow-directing vessel as set forth in claim 14, wherein the capsule is a one-piece body and the cup is one-piece body. 17. A flow-directing vessel as set forth in claim 16, wherein the cup and the capsule are not made of the same material and wherein the capsule is made of a durable corrosion-resistant material. 18. A flow-directing vessel as set forth in claim 13, wherein the cup surrounds the capsule. 19. A flow-directing vessel as set forth in claim 13 and a solenoid assembly controlling movement of the plunger. 20. A flow-directing vessel as set forth in claim 13, wherein a solenoid assembly mechanically biases the plunger to a closed position sealing the orifice and, when energized, moves to the plunger to an opened position unsealing the orifice. 21. A flow-directing vessel as set forth in claim 13 and a receiving member comprising an interfacing cavity; the interfacing cavity comprising a cylindrical wall with a threaded portion, a bottom wall structure below the threaded portion in the cylindrical wall, a supply passage situated in the bottom wall structure, and a delivery passage situated in the bottom wall structure; the sleeve's threaded portion engaging the threaded portion of the cylindrical wall of the interfacing cavity; and the chamber communicating with the delivery passage and the entrance communicating with the supply passage. 22.
