MECHANICALLY-ACTUATED PNEUMATIC VALVE

摘要

A mechanically-actuated pneumatic valve can comprise an input port receiving compressed gas and one or more output ports. A face seal can be arranged in the valve body and be configured to move between two positions. In a first position, the face seal can permit compressed gas from the input port to be supplied to a first output port. In a second position, the face seal can vent compressed gas from the valve body through an exhaust port. An actuator, such as a pin or pin-shaped actuator, for example, can be configured and arranged to move the face seal from the first position to the second position. An actuator of an operative device could be configured to physically contact a surface of the pin-shaped actuator and drive the face seal to its second position.

主权项

1. A mechanical pneumatic valve for a pneumatic gun, comprising:
a body comprising a plurality of ports for communicating compressed gas, said plurality of ports comprising an exhaust port; a contact surface surrounding the exhaust port; a face seal configured to abut against the contact surface of the exhaust port and seal the exhaust port when the mechanical pneumatic valve is in a non-actuated state; and a mechanically-actuated valve actuator configured to actuate the mechanical pneumatic valve when the mechanical pneumatic valve is operatively arranged in the pneumatic gun, wherein the valve actuator is configured to move the face seal away from the contact surface of the exhaust port to exhaust compressed gas through the exhaust port, without the face seal sliding along the contact surface of the exhaust port.
