摘要： The invention relates to an electromagnetic hydraulic valve (1), particularly a proportional valve for controlling a device for adjusting the rotation angle of a camshaft relative to a crankshaft of an internal combustion engine, comprised, on the one hand, of an electromagnet (2) with a hollow cylindrical magnet housing (4), at least one coil winding (5) and an axially moving armature (6) as well as with a first and a second pole shoe (7, 8) and, on the other hand, is comprised of a valve part (3) with a hollow cylindrical valve housing (9) inside of which a control plunger (12) is housed that can be axially displaced by the armature (6) of the electromagnet (2) via a push rod (11). According to the invention, a bush (17) comprised of a bottom (18) and of a hollow cylindrical side wall (19) is placed on the end of the control plunger (12) lying in the direction of the push rod (11). Said bush has a hardness greater than that of the control plunger (12). This constructed plunger makes it possible to manufacture the valve part (3) considerably easier than in the prior art.

摘要： A spool valve is provided with a stem portion (60f) that defines a fluid passageway (56f) formed by either (a) a single central support having a non-cylindrical curved surface shaped hydrodynamically, or (b) only a pair of sidewalls with, preferably, interior surfaces that are also shaped hydrodynamically. These stem passageways, which are designed to facilitate the flow of high-speed/high-pressure fluids controlled by the valve, are maintained in a predetermined orientation relative to the ports of the valve cylinders by a mechanism preferably including (a) a cam-following roller (66a) supported in a tang (62a) fixed to each spool and (b) a two-element cam that captures the roller (66a) within two of the parallel sides of a cam-track groove formed in the respective interior surfaces of each cam element.

摘要： A booster pilot valve (10) operable at ultra low power levels is provided. The booster valve (10) includes a movable spool (160) capable of directing a fluid flow (170) to at least two different paths (118, 119). The booster valve (10) may be coupled to a piezotronic three-way valve (40), which controls the movement of the spool (160) by redirecting a main fluid flow (170) along different paths to create a force on the spool (160). The piezotronic valve (40) is capable of actuation at very low power levels such as might be provided by a Profibus PA or other Bus system.

摘要： The present invention relates to a control valve for controlling flow of hydraulic fluid. The control valve comprises: a valve housing (10); a sleeve (11) slidable in a valve chamber in the valve housing (10); a first fluid conduit (12) for connecting the valve chamber to a source of pressurised hydraulic fluid; a second fluid conduit (14) for connecting the valve chamber to a fluid return for returning hydraulic fluid to a reservoir; and a third fluid conduit (16) for connecting the valve chamber to deliver hydraulic fluid to and receive hydraulic fluid from apparatus which uses the hydraulic fluid flow controlled by the control valve. The sleeve (11) is a tubular sleeve having a tubular passage therethrough. The valve housing has a pair of spaced apart valve seat surfaces (22, 23), a first valve seat surface (22) which is engageable by a first end of the tubular sleeve (11) and a second valve seat surface (23) which is engageable by a second end of the tubular sleeve (11). The third fluid conduit (16) opens on to the valve chamber by way of a port which is surrounded by the first valve seat surface (22).

摘要： A pressure control valve includes: a sleeve (62) on which an input port (P1), an output port (P2), and drain ports (P3,P4) are formed; and a linear solenoid portion (11) for generating thrust. The pressure control valve further includes: a first spool (26), which advances and retreats within the sleeve (62), for receiving the thrust, regulating input pressure input to the input port, and outputting the regulated output pressure from the output port; and a second spool (27), which advances and retreats within the sleeve (62), for receiving the thrust, and selectively applying output pressure to the first spool. The output pressure is selectively applied to the first spool, thereby doing away with the need for a control valve or the like. This simplifies the oil pressure circuit for generating control pressure, and allows control pressure to be generated in a stable manner, and the size of the pressure control valve to be reduced.

摘要： A statically and dynamically pressure balanced fluid control valve (10). The valve (10) contains a spool (24) that is moved within an inner chamber (26) of a valve housing (28) by a pair of solenoids (34, 36). The ports are symmetrically located on each side of a center port (20), wherein the resultant fluid forces on the spool (24) are in opposite directions. The opposing forces create a net fluid force of approximately zero, so that the spool (24) is dynamically pressure balanced when the valve (10) is switched to a new position. The spool (24) also has an inner channel (40) and a pair of end openings (42) that are in fluid communication with the inner chamber (26) of the valve (10). When the spool (24) is pulled to a new position, the end openings (42) and inner channel (40) allow fluid within the inner chamber (26) to flow out of the space between the end of the spool (24) and the housing (28).

摘要： A proportional, pilot-operated directional valve has a sleeve with at least four sets of radial holes, and a spool disposed within the sleeve, with a channel being defined between the spool and the sleeve. The spool has at least two sets of radial holes, and the exterior surface of the spool has annular protrusions, each being in at least partial contact with the inner wall of the sleeve. When the valve is in an open position, the first set of radial holes of the sleeve is in communication with one of the two sets of radial holes of the spool, the second and third sets of radial holes of the sleeve are each at least in partial communication with the channel, and the fourth set of radial holes of the sleeve is in communication with the other of the two sets of radial holes of the spool. The spool may be kept in an open position by pressure from a flow of fluid that is provided at one end of the sleeve.
