摘要： The invention relates to a thermostat valve arrangement for the cooling circuit of an internal combustion engine, wherein the main valve member of main valve is moveably mounted in a housing, said member being able to be pressed against a main valve seat by a spring, wherein a bypass valve member of a bypass valve is also provided, said bypass valve member co-operating with a bypass valve in the housing, and wherein a first section of an expansion material element (DWE) co-operates with a counter bearing which is fixed to the housing and a second section co-operates with the main valve member and the bypass valve member. The main valve or bypass valve are selectively closed or opened in order to produce the cooling circuit of an internal combustion engine by means of a cooler or a bypass. The main valve seat is formed by a conical seat surface in the housing. The main valve member forms a valve unit with an axially distanced piston-shaped bypass valve member, said valve unit receiving the expansion material element in an axial recess in one direction in an axially secure manner. The other end of the expansion material element is supported by a counter bearing of the housing, the valve unit is displaceably and axially guided in a guide component which is axially supported in the housing. A valve spring operates between the valve unit and the guide component. Said valve spring pretenses the unit in the direction of the main valve seat and the valve unit and the guide component are provided with interacting stops which are used to limit movement of the parts away from each other. The piston-shaped bypass valve co-operates with a hollow cylindrical section of the guide component.

摘要： In a poppet check valve (10), a cylindrical inlet passage (46) connects axially with a valve chamber (56) and a shoulder (50) at the juncture between the inlet passage and the chamber defining an annular valve seat (54). A relatively thin disc-like valve element (60) in the valve chamber (56) has a generally circular imperforate central section (66) of a diameter greater than the diameter of the inlet opening (52) but less than the diameter of the valve chamber (56). A pluarlity of legs (68) extend radially from the periphery of the central section (66) into sliding engagement with the inner wall (48) of the valve chamber (54). A circular seal element (72) is joined to one side of the central section (66) and is maintained under a bias toward the seat by a coil spring (62) mounted in the valve chamber (56). Between the spring (62) and the valve element (60) is a stop member (64) including a plurality of radially spaced, axially extending force applying elements (98) engaging the central section (66) of the valve element (60). The stop member (64) also includes a guide surface (95) radially outwardly of the force-applying elements (98) for sliding engagement with the wall (48) of the valve chamber (56) at a location axially spaced from the valve element (60).

摘要： A flame-retardant pressure equalizing valve contains a valve body (3) that is guided in a housing (1). Under the influence of excess pressure, the valve body (3) is displaceable from a closing position into a blow-off position. The housing (1) and the valve body (3) form a first closure (8) and, in series therewith, a second closure (9). The surface of the second closure (9) projected in the opening direction (7) is larger than the surface of the first closure (8) projected in the opening direction (7) and the first closure (8) opens during opening before the second closure (9), so that, during opening, the excess pressure acts on an enlarged surface and the valve is opened promptly. The second closure (9) is spaced from the first closure (8) in opening direction (7). As a result, a better closing behavior and an increased outlet velocity of the outflowing gas are obtained.

摘要： The pressure retaining valve has a housing (1) with an inlet channel (4) and an outlet channel (5) which can be connected thereto. A valve piston (8) with a valve spindle (11) is fitted to move in the housing. The valve piston (8) is loaded by a spring (7) towards the valve seat (3) and, in its closed position, shuts off the connection between the housing inlet (4) and outlet (5) channels. A diaphragm (9') separating the spring (7) and the valve piston (8) is mounted in the housing (1). Between the separating diaphragm (9') and the valve seat (3) there is a guide plate (10) movably guiding the valve spindle (8). It surrounds the valve spindle (8) to form a narrow annular gap (12) acting as a choke, thus preventing control oscillations. To make the valve proof against counter-pressure, the area of the valve seat (3) corresponds to the active area of the separating diaphragm (9').

摘要： A pressure relief valve comprises a housing (10) having a stepped bore comprising a first portion (18) and a second portion (18) extending through the housing (10). An annular shoulder is formed in the housing to define a valve seat (19). A piston (22) is slidable in the housing (10) and a spring (30) biases the piston (22) into engagement with the seat (19). The spring (30) is retained by a cap (32). A seal between the piston (22) and the seat (19) is made by an 0-ring (25) located in an annular groove (23). Passageways (37) adjacent the seat (19) communicate the exterior and interior of the housing (10). The total cross-sectional area of the passageways (37) is less than the area of the second bore portion (20) causing, in operation, a pressure build-up in the first portion (18) below the piston (22) which increases piston movement.
The pressure relief valve is particularly suitable for use on life rafts.-
