摘要

The fluid flow switching apparatus includes a housing defining a chamber, a bore in communication with the chamber, fluid inlet and outlet ports respectively in communication with the chamber and bore, and a valve body movable within the chamber and carrying a sealing means for sealing about the bore. The valve body carries a pin which projects laterally into a cam track formed in the housing and which serves to releasably lock the valve body in a position enabling flow between the inlet and outlet ports through the chamber and bore and in a valve closed position preventing flow between the inlet and outlet ports. The valve body is movable manually between the valve open and closed positions by consecutive depressions of a push key connected to the valve body.
