摘要： A check valve comprising a poppet urged by a conical spring to annularly seal uniformly around its entire periphery to assure more uniform cracking pressure about its entire periphery. The cracking pressure may be adjusted by means of an adjustable plate which reduces the length of the conical spring and thereby increase the amount of force exerted by the spring onto the poppet into sealing engagement, thereby increasing the cracking pressure.

摘要： A piston check valve (10, 20) for use in a system which conveys abrasive materials includes a gland nut (22) which connects the valve to the piping system, a valve body (24) mounted on the gland nut (22), a valve seat (14, 26) mounted on the valve body (24), and a piston (38) mounted within the valve body (24). The piston (38) can translate within the through bore (36) of the valve seat (14, 26) and has a shaft (40) and a head (42) which contacts the first end (30) of the valve seat (14, 26) when the valve is closed. A coil spring (52) is located within the through bore (36) of the valve seat (14, 26) and biases the valve closed. A first O-ring (56) is mounted on the first end (30) of the valve seat (14, 26) and is sufficiently wide to prevent sufficient quantities of chips from becoming lodged within the surface of the inner O-ring (56) to form a hard bridge across the O-ring (56), allowing erosion of the valve sealing surfaces. The first end (30) of the valve seat (14, 26) has an O-ring groove (58) which receives the O-ring (56). A second O-ring (60) can be mounted on the first end (30) of the valve seat (14, 26) at the outer periphery of the valve seat (14, 26).

摘要： A positive displacement pump (50) includes a relief valve comprising a valve seat (61), a needle (62) within the valve seat, a spring (63) forcing the needle within the valve seat, a set screw (65) pressing the spring against the needle and a spacer (64) for mounting the set screw to the housing of the positive displacement pump. The valve seat threadably connects within the relief valve passageway to prevent the erosion of the passageway. The valve seat may be constructed from a plastic, hard rubber, or metal material and include a rubberized seal secured at one end of the valve seat. When the valve seat erodes to a point where it provides an insufficient seat for the needle, it is removed from within the relief valve passageway and replaced with a similar valve seat. By protecting the relief valve passageway from erosion by using an inexpensive, removable, and disposable valve seat, costly disposal or machining of the housing of the positive displacement pump is avoided.

摘要： The invention relates to a safety device for limiting the pressure of a compressor that operates with variable stroke or variable displacement. The tilt of the wobble plate or the swash plate is varied at least by the difference between the high pressure in the discharge pressure zone (11) and the driving chamber pressure (16), optionally by the difference between the driving chamber pressure and the suction pressure. The safety device is provided with a supply connection between the discharge pressure zone (11) and the driving chamber pressure (16), with a valve device disposed in said supply connection, and optionally with a bypass throttle.

摘要： The invention relates to a device (10) for controlling pressure. The inventive device comprises a housing (11) and an axially moveable closing body (12) that is received therein. The housing (11) is provided with at least one inlet (21) for pressure means and one outlet (22) for pressure means. The closing body (12) is pre-stressed against a valve seat (11') in the housing by means of a coil spring (14). At least one compensation means for the coil spring (14) is provided. According to the invention, a compensation element (15) is provided as the compensation means. Said element is axially arranged between the closing body (12) and an end of the coil spring (14), whereby said end faces the closing body (12). The compensation element rests on the inner wall of the housing (11) in a springy manner and in the radial direction and contacts the closing body (12) in a preferably frictionally engaged manner and with the central area (15') thereof. The central area (15') of the compensation element (15) is designed in a dome-shaped manner. Radially protruding spring arms (15'') are arranged peripherally in relation to the central area (15') of the compensation element (15).

摘要： A recirculation valve (10) for cooling a centrifugal pump. The invention comprises a valve casing having a first chamber (14) for connection to a centrifugal pump and a second chamber (16) for connection to a fluid outlet, a recirculation port (30) for redirecting fluid from the first chamber (14) to the centrifugal pump. Between the first and second chambers (14, 16) is a check valve means for permitting fluid flow from the first to the second chamber. Connected to the check valve means (24) is a hollow cylindrical valve stem (42) permitting fluid flow from the first chamber (14) to the second (16) chamber. The check valve means is comprised of a circular disc (34) in first chamber (14).

摘要： L'invention se rapporte à une soupape de recirculation (10) destinée au refroidissement d'une pompe centrifuge. L'invention se compose d'un corps de soupape possédant une première chambre (14) se reliant à une pompe centrifuge et une seconde chambre (16) se reliant à une sortie de fluide, un orifice de recirculation (30) qui redirige le fluide de la première chambre (14) vers la pompe centrifuge. Entre la première et la seconde chambre (14, 16) se trouve un élément de soupape de non-retour permettant l'écoulement du fluide de la première vers la seconde chambre. Une tige de soupape cylindrique creuse (42) reliée à l'élément de soupape de non-retour (24) permet l'écoulement du fluide de la première chambre (14) vers la seconde chambre (16). L'élément de soupape de non-retour comporte un disque (34) dans la première chambre (14).
