<p>The pressure regulating and by- passing device for heat engine lubricating circuit comprises at least one lubrication filter (5) and a hollow connector (16). The hollow connector contains a control valve (6) for obturating at least one aperture (23, 24). The least one aperture communicates the delivery circuit of the oil pump (3) of the engine (1) with a bore of the hollow connector leading to an oil inlet for said engine. The hollow connector supports a heat exchange intermediary part (4) and an oil filter (5). Normally oil delivered by the pump (3) passes through the heat exchanger (4) and filter (5) into the bore of the connector for supply to the oil inlet. At start-up, when the oil is viscous, the oil passes through the apertures (23, 24) under the control of a pressure or temperature control valve (6). <IMAGE></p> |
