| description | The disclosed vacuum valve device comprises a housing having a wall with a flat valve surface, a plate-like valve carriage having a cavity therein facing the valve surface, the wall having vacuum distribution ports therein, and a soft resilient rubber-like, plate-like valve member snugly received in the cavity and having vacuum distribution passages thereon. The valve member is slidable along the valve surface for selectively interconnecting the ports. The valve carriage has tractor elements in the form of pins thereon projecting into the cavity. The valve member has blind openings therein for receiving the pins to transmit driving forces between the carriage and the valve member. A keying pin is also formed on the carriage and is received in a uniquely located blind opening in the valve member. The pins have flat surfaces to provide passages for the escape of air that would otherwise be trapped in the openings by the pins. |
