Valve
First Claim
1. A valve comprising:
- a housing having an inlet, an outlet and a ram receiving chamber;
a ram having a first end and a second end, the ram is slidably supported in the ram receiving chamber, the ram has a central pin on the second end of the ram;
an actuating element being connected to the ram;
a plate being fixedly connected to the housing, the plate has a central bore, the ram and the plate selectively abut to form a valve seat;
wherein the inlet is in fluid communication with the ram receiving chamber, the ram has an outer wall, a portion of the ram receiving chamber adjacent to the first end of the ram is in fluid communication with a portion of the ram receiving chamber adjacent to the second end of the ram;
in the closed position the ram abuts with the plate ;
the pin protrudes through the central bore in the plate, in the open position the actuating element displaces the ram such that the ram is spaced from the plate.

Abstract
A valve includes a housing having an inlet, an outlet and a ram receiving chamber. A ram has a first end and a second end and is slidably supported in the ram receiving chamber. The ram has a central pin on the second end of the ram. An actuating element is connected to the ram. A plate is fixedly connected to the housing. The plate has a central bore. The plate and the ram selectively abut to form a valve seat. The inlet is in fluid communication with the ram receiving chamber. The ram has an outer wall. Fluid communicates between a portion of the ram receiving chamber adjacent to the first end of the ram and a portion of the ram receiving chamber adjacent to the second end of the ram. In the closed position, the ram abuts with the plate. The pin protrudes through the central bore in the plate. In the open position, the actuating element displaces the ram such that the ram is spaced from the plate.
