ABSTRACT:
Used in the automobile industry, and more specifically in the driver's cab heating system, the valve is installed between the link between the engine and the radiator and the cab's heating system. It consists of a housing unit (1) which has a circular compartment (2) which houses the rotor (25) which has a side wall which protrudes a few millimeters (28) and has attached to it, by means of an “8”-shaped lever (36), a sealing unit, consisting of an O ring (33) and its support (34). This sealing unit and the side wall (28) are responsible for blocking off the flow of liquid to the cab's heating system and the by-pass, respectively. The previously mentioned compartment has a tubular inlet (3) and outlet (5) and is attached by a linking channel (14) to the adjacent cavity (10), to which is attached an outlet tube (11) and a return opening (13) and the rotor (25) is operated manually by means of an external lever (42).
