Abstract:
A suction control valve comprising:a valve body having a suction source access port, a primary suction device access port, and a fluid flow passage for allowing fluid flow passage between said suction source access port and said primary suction device access port;an ancillary suction device access port in fluid flow connection with said fluid flow passage;a valve core having a plurality of fluid flow channels formed through a center portion thereof, the valve core being positioned at least partially within said valve body for movement relative thereto between at least a first position in which said primary suction device access port and said ancillary suction device access port are closed against fluid flow therethrough, a second position in which said primary suction device access port is open to fluid flow therethrough and said ancillary suction device access port is closed to fluid flow therethrough, and a third position in which said primary suction device access port is closed against fluid flow therethrough and said ancillary suction device access port is open to fluid flow therethrough;a compression spring positioned to bias said valve core against movement thereof to said second position from said first position; andan actuation button operably positioned relative to said valve core for moving said valve core from said first position to said second or third positions.
