摘要： A hydraulic circuit (1) associated with an internal combustion engine (M) comprising a main cooling circuit (2) of the engine (M) provided with a circulation pump (4) for a cooling fluid, and an auxiliary preheating circuit (3) branched from the main circuit (2); the pump (4) is a rotary volumetric pump dimensioned so as to generate, at least during a warm-up transient of the engine (M), a flow rate greater than that required for the cooling of the engine (M); at least one fraction of the flow rate generated by the pump is sent to the auxiliary circuit (3) where it recovers heat from a fluid (23; 26) at higher temperature, such as the exhaust gases and/or the supercharging compressed air of the engine (M), and gives it to a fluid (24) at lower temperature, such as for example the engine oil or the passenger compartment air.

摘要： A mechanical seal (1; 40; 59) configured to be interposed between a rotating shaft (2) and a fixed body (3) provided with an aperture (4) through which the shaft (2) extends, particularly for a recirculation pump of the cooling liquid of a motor, comprising a fixed part (5) and a rotating part (7) provided with respective sealing rings (6, 8) cooperating frontally with each other under an axial load exerted by a spring (33), and an absorbing material element (35) for absorbing at least temporarily possible leaks of fluid leaking through the sealing rings (6, 8) fixed to the fixed part (5).
