Abstract

PURPOSE: To eliminate compression loss of a valve system through easily creating a state of zero pressure on a valve seat, by forming a through hole communicated with a suction groove on a base plate and fitting an adjust screw in the hole to press the holder of a suction valve with the screw tip.
CONSTITUTION: A valve system used for a diaphragm pump forms a pump chamber 4 by holding a diaphragm 1 between a base plate 2 and holding plate 3, and a suction groove 14 on the base plate 2, a suction valve 6 solidly formed on the diaphragm 1 and a suction port 7 made on the holding plate compose a suction unit, and the system also has a motor 12 for driving the diaphragm 1. A through hole 15 communicated with the suction groove 14 is made on the base plate 2. An adjust screw 16 is fitted in the hole 15 to press the holding portion 6a of the suction valve 6 with the screw tip. This construction eliminates a clearance between the holding plate 3 and the holding portion 6a of suction valve 6 and easily produce a zero pressure contact with a valve seat.
