Abstract

PURPOSE: In a diaphragm pump suitable for supplying a secondary air to the engine to provide a complete prevention of harmful movements for the diaphragm such as a lateral rocking and swinging etc. in the central disk and to keep a stable reciprocation of the diaphragm.
CONSTITUTION: Diaphragms 2 and 3 are arranged in parallel at both sides of the housing 1. Covers 4 and 5 are provided outside of the diaphragms to sealingly hode a circumference of the diaphragm. At the center of the housing 1 is rotatably supported a shaft 7. The shaft 7 is connected to central disks 10 and 11 arranged at the central portion of the diaphragms 2 and 3, and the pressing plates 12a and 12b via the circular cam 16 eccentrically fixed to the shaft 7. In the shaft 7 are arranged two pairs of parallel supporting axes 70a, 70b and 71a and 71b, ends of the crescent 72a, 72b, 73a and 73b are supported by these axes, the circular or arcular surfaces at the other ends are slidably contacted with the inner wall of the housing 1 via belt-like resilient plates 76a, 76b, 77a and 77b.
