Abstract
A pneumatic valve assembly including a valve body having an inlet port in fluid communication with a source of pressurized air and a valve bore extending axially within the valve body with a valve member movable between predetermined positions within the valve bore. The valve member selectively movable to direct a flow of pressurized air from the inlet port through the valve bore to an outlet port. A valve element is disposed upon the valve member having an angular valve sealing surface, and a valve seat is defined in the valve bore formed at an oblique angle to provide a sealing contact with the valve sealing surface when the valve member is in a closed position thereby interrupting said flow of pressurized air.
Claims14
A pneumatic valve assembly comprising:
- a valve body having a pressurized air supply inlet port in fluid communication with a source of pressurized air;
- a valve bore extending axially within said valve body and a valve member movable between predetermined positions within said valve bore to selectively direct a flow of pressurized air from said inlet port through said valve bore to at least one outlet port;
- an at least one valve element disposed upon said valve member, said at least one valve element having an angular valve sealing surface;
- and
- at least one valve seat defined in said valve bore and formed at an angle oblique to said valve bore and adapted to provide a sealing contact with said valve sealing surface of said valve element when said valve member is in a closed position thereby interrupting said flow of pressurized air.
