ABSTRACT:
A suction control valve is disclosed which includes a primary suction device access and an ancillary suction device access. The valve includes an actuator which is movable between a first position in which the primary access is closed against suction pressure therethrough, to a second position in which the primary access is open to suction pressure therethrough, or alternatively, to a third position in which the primary access port remains closed to suction pressure therethrough and the actuator becomes locked against movement into the second position. When the actuator is in the first position, atmospheric air can pass through the valve and into the suction pressure source in such a manner that a "hissing" auditory signal is generated, indicative of the presence of suction pressure within the valve. When the actuator is in the second or third positions, the "hissing" is prevented. The valve also includes an ancillary access port which allows the attachment of an ancillary suction device such as a Yankauer device to the valve without the necessity of removing the primary suction device from the primary device access port.
