摘要： A joint for systems for transporting a high temperature heat-transfer fluid is provided. The joint includes a fixed conduit, a first sealing ring joined to the fixed conduit, a rotatable conduit in abutment with the sealing ring, and an outer casing delimiting a chamber. A contact region between the rotatable conduit and the first sealing ring is arranged in the chamber. The outer casing is sealingly engaged with the rotatable conduit by a second sealing ring and with the fixed conduit.

摘要： A mechanical seal includes: a fixed portion with a receptacle and a first seal ring provided on the receptacle, a rotary portion with a sleeve and a second seal ring provided on the sleeve, a cup mounted inside the receptacle with the possibility of sliding in an axial direction, a gasket housed in the cup, and a spring axially compressed between the receptacle and the cup. The spring has a first end constrained to the cup by means of first constraint means, and a second end constrained to the receptacle by means of second constraint means, in such a way that the spring opposes a rotation of the cup relative to the receptacle.

摘要： A seal designed for insertion between a rotating shaft and a fixed casing having an opening through which the shaft is fitted, the seal having a sleeve designed to fit onto the shaft; a first sealing ring fitted to the sleeve; a cup designed to fit inside the opening; and a second sealing ring connected to the cup by a bellows of elastomeric material; the first and second sealing rings cooperate frontally with each other under the axial load exerted by a spring interposed between the cup and the second sealing ring; and the bellows is connected in angularly free manner to the cup to prevent self-induced torsional oscillation and noise resulting from it.

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

摘要： A mechanical seal having a first seal ring, which is mounted in a receptacle of a fixed part, and a second seal ring, which is mounted in a sleeve of a rotary part having a fixing portion fixed to a rotary shaft. The second seal ring extends radially inwards relative to the fixing portion of the sleeve, above an upper ending surface of the rotary shaft. The first seal ring is disposed above the second seal ring in such a way that the sliding surfaces of the first seal ring and of the second seal ring are in mutual contact. The sliding surfaces of the first seal ring and of the second seal ring have a mean diameter that is lower than an external diameter of the rotary shaft.
