초록 ▼

A reciprocating piston with an integral valve moves in a first direction within a cylinder to pressurize viscous material contained therein, such as ice cream or the like, thereby pushing it out of a dispensing nozzle located at one end of the cylinder while simultaneously extracting viscous material from a collapsible container into the other end of the cylinder by suctioning the material from the container. When the piston moves in a second direction, the integral valve opens to allow the piston to pass through the previously suctioned viscous material then within the cylinder. The dispensing nozzle includes a normally closed, spring-biased valve opened by the force of the pressurized material, closing of the valve being assisted by a transient suction force occurring as the valved piston beings to move in the second direction through the material. Suctioning the material from the collapsible container, as opposed to compressing the container to expel the material, is preferable when the material contains entrapped gas, as is the case with ice cream, since repeated compression of such containerized material can diminish its quality.

대표청구항 ▼

A dispensing valve for discharging viscous material pushed toward and moved away from the valve comprising: a valve body providing an inlet port, an outlet port, and a chamber in fluid communication with said ports, said viscous material being flowable from said inlet port to said outlet port via said chamber when said valve is in an open condition; a poppet member contained within the valve body and being movable between a closed position when seated and sealed against said outlet port to preclude viscous material flow therethrough, and an open position when unseated and spaced from said outlet port to permit viscous material flow therethrough, said movable poppet member providing a surface acted upon by said viscous material within said chamber; and a biasing member contained within said valve body and biasing said poppet member toward its closed position seated and sealed against said outlet port, said poppet member being movable to its open position solely by viscous material pressure against said surface wherein said valve opens, said poppet member being movable to its closed position by the combination of said biasing and a negative pressure or suction force applied to said surface by said viscous material as a portion of said viscous material is withdrawn from said chamber via said inlet port, wherein said valve closes.
