ABSTRACT:
The present invention has a by-pass thermostat assembly (1) that is connected to the oil circulation system of an automatic hydraulic transmission system of an internal combustion or other engine. The assembly includes a block or a case (4) with an inner housing (5) to locate a thermostatic valve within a casing (7) that acts as a piston sliding along the housing, and being biased by a spring. The housing (5) is covered by an end plug (11). The thermostatic valve is located in the housing, and in conjunction with an inner housing (5), has are two parallel channels (13and14) which are open in the posterior part of the block or case (4), where they receive two conduits (15) coupling to an oil/air exchanger, the two channels being in communication with respective holes (16and17), which are coupled to the transmission (18) through appropriate connections (20), such that the thermostatic valve is responsive to the oil temperature, opening the channel to the oil/air exchanger when the oil is hot, and closing when the oil is cold to by-pass the cooling circuit such that an optimum transmission oil temperature is achieved.
