초록 ▼

A dry break coupling for connecting a pair of fluid conduits includes first and second housings adapted for connection to the respective conduits. The first housing includes a piston supported for axial sliding movement between a first position wherein fluid flow through the first housing is blocked and a second position wherein fluid is free to flow through the first housing. The second housing includes a poppet supported for axial movement between a first position wherein fluid flow through the second housing is blocked and a second position wherein fluid is free to flow through the second housing. A handle is provided on the first housing for moving the piston between the first and second positions therefor and the poppet is engaged by the piston and moved to its second position in response to axial movement of the piston from the first to the second position therefor. The housings are coupled together by a coacting pin and slot connection including an axially extended pin on one housing, a circumferentially extended slot on the other housing, and portions for axially securing the housings in axial engagement in response to circumferential movement of the pin in the slot. The piston is generally cylindrical in shape having a closed outer end and a plurality of openings through its peripheral surface adjacent its outer end for fluid flow through the openings and piston when the piston is in the second position therefor. First and second stop means are provided for axially retaining the piston and poppet in the first positions therefor. The stop means are disengageable in response to pivotal movement between the housings as they are connected. The invention also includes a device for alternately locking the handle of the first housing in positions corresponding to the first and second position of the piston and a cap adapted to be locked onto the second housing when the housings are disconnected.
