ABSTRACT:
A suction regulator having an elongated hollow body with interconnected distal and proximal ports at opposite ends thereof, each adapted to be connected to an end of a flexible conduits The proximal port is adapted for conduit connection to a vacuum source and the distal port is adapted for conduit connection to a device needing suction control. An elongated slot is provided in the hollow body and extends through a wall of the hollow body. The slot has converging straight side walls extending over a majority of a length of the slot and from a wide end to a narrow end thereof. The hollow body is provided with an axially extending guideway thereon which is operatively connected to the gate member and a guide structure thereon for guiding the gate member axially relative to the hollow body between a first position oriented spaced from the wide end of the slot so as to provide unobstructed access to the slot to thereby effect a minimum suction rate at the distal port and a second position fully obstructing access to the slot to thereby effect a maximum suction rate at the distal port.
