Abstract
PURPOSE: To obtain sufficient durability and necessary delivery amount and obtain a pump which can be installed easily onto an engine by forming a pump chamber from a diaphragm and housing wall part.
CONSTITUTION: The apparatus consists of housings 1, 2, and 3, a pair of diaphragms 15a and 15b, a center disc 13, rocking rod 11, supporting shaft 12, an eccentric circular cam 4 which serves as driving means, and pump chambers 19a and 19b which are equipped with a pair of diaphragms 15a and 15b and the housing wall which is opposed to said diaphragms and performs compression conveyance of the secondary air. This constitution allows the delivery operation in two times in one reciprocation of a center disc 13, and the surface area of the diaphragm in the same capacity can be reduced half. Further, as the rocking rod performs lever movement, the distance from the supporting shaft to the cam shaft 14a can be reduced, and the pump can be miniaturized.
