    Abstract: A hydraulic circuit supplies pressurized hydraulic fluid to and from a torque converter that is operatively associated with a lockup clutch. The torque converter is disposed upstream of an outlet regulator that maintains a predetermined pressure in the torque converter. Power transmission in a powertrain can be directed through the torque converter during a hydrodynamic mode and can be directed through the lockup clutch during lockup mode. To switch between the hydrodynamic mode and the lockup mode, the hydraulic circuit includes a diverter valve to selectively direct pressurized hydraulic fluid between the torque converter and the lockup clutch. When operating in the lockup mode, the diverter valve further diverts hydraulic fluid discharged for the torque converter to bypass the outlet regulator disposed downstream of the torque converter.

  • Publication number: 20120285546
    Abstract: The invention relates to a throttling valve comprising a fluid inlet (29) and a fluid outlet (27). The throttling valve is arranged to control a flux of a fluid stream flowing via a flow path from the fluid inlet (29) to the fluid outlet (27). The flow path comprises a plurality of openings (330) which, in use, create a pressure reduction over the throttling valve and thereby a cooling effect of the fluid. The openings (330) widen in a downstream direction.

  • Patent number: 8276612
    Abstract: A system and method for controlling fluid pressure downstream a main valve includes associating a variable orifice with the main valve such that the variable orifice opens as the main valve is opened and closes as the main valve is closed. A fluid stream taken from a fluid inlet of the main valve is passed to an inlet of the variable orifice. A fixed orifice is in fluid communication with an outlet of the variable orifice. A pressure differential between the inlet and outlet of a fixed orifice is detected by a control pilot device, which hydraulically opens or closes the main valve in response to the detected fixed orifice pressure differential between low pressure and high pressure set points.

  • Patent number: 8261770
    Abstract: A flush valve for a waste water system comprises a valve including a fluid inlet, a fluid outlet and a main valve element adapted for movement to allow fluid flow between the fluid inlet and the fluid outlet based on a pressure differential across a portion of the main valve element. The valve also includes a vent system comprising a control chamber in flow communication with the fluid inlet of the valve and a vent outlet in flow communication with the fluid outlet of the valve, and a solenoid for venting fluid venting fluid from the control chamber to the fluid outlet. A pressure sensor, such as an electronic pressure transducer, senses the fluid pressure of fluid within the vent system and regulates water flow through the valve based on the sensed fluid pressure so as to deliver a predetermined quantity of water through the valve.

  • Publication number: 20120111425
    Abstract: Example internal relief valves for use with fluid regulators are described. An example internal relief valve includes a relief valve seat coupled to a first end of the relief valve stem and to engage a first side of a sensing apparatus to prevent fluid flow between the first side of the sensing apparatus and a second side of the sensing apparatus when the internal relief valve is in a closed position. A bleed hole within a surface of the sensing apparatus and separate from the opening of the sensing apparatus is dimensioned to provide a controlled flow rate between the first side and the second side of the sensing apparatus when the internal relief valve is in an open position. A seal is disposed along a body of the relief valve stem upstream from the bleed hole and the valve seat to prevent fluid flow between the first side of the sensing apparatus and the second side of the sensing apparatus via the opening of the sensing apparatus when the relief valve is in the open position.

  • Publication number: 20120006427
    Abstract: The invention relates to a hydraulic valve device having a fluid connection arrangement (10) and having a displaceable control device (16) for at least partially actuating connections of the fluid connection arrangement (10), wherein the control device (16) can be actuated by two opposing pilot valves and is held in the neutral position thereof by centering springs. By providing at least one throttle position (da1, db1) between each pilot valve and the control device that can be connected for fluid flow between a load probe connection (LFA) and a load indicating connection (LMA) or a load probe connection (LFB), a hydraulic valve device enables fine control for moving loads.

    Abstract: A system for hydraulically managing fluid pressure between selected set points includes a pilot control system operably coupled to a main valve. The pilot control system includes at least one fluid conduit, a variable orifice assembly, and a control pilot valve apparatus. Fluid is passed through a fixed orifice and into a first chamber of the control pilot valve apparatus. Fluid is passed through the variable orifice of the variable orifice assembly and into a second chamber of the control pilot valve apparatus. The main valve is hydraulically opened or closed in response to a pressure differential between the first and second chambers of the control pilot valve apparatus so as to manage fluid pressure downstream of the main valve between the selected upper and lower set points.

  • Publication number: 20100155633
    Abstract: A control valve includes a main poppet that moves in response to pressure in a primary control chamber and thereby controls the flow of fluid through a valve seat between first and second ports. A passageway extends between the second port and the primary control chamber and includes a variable flow restriction that decreases as the main poppet moves away from the valve seat. An electrohydraulic pilot valve has a pilot poppet which controls fluid flow from the primary control chamber to the first port in response to pressure in a pilot control chamber. A sub-pilot valve selectively releases pressure in the pilot control chamber to operate the pilot poppet to open and close a path between the inlet and the outlet. Using an electrohydraulic pilot valve enables the main poppet to operate quickly in controlling large fluid flow rates. Unidirectional and bidirectional versions of the control valve are described.

  • Patent number: 7703477
    Abstract: A fluid control valve for use with apparatus for medical use. Commercially available valves which operate by electrical, hydraulic or pneumatic means are often expensive and bulky. They may require excessive power to operate them and can be noisy during operation due to moving parts and fluid flow through internal pathways. The valve of the present invention has a valve seal (1) mounted between inlet (A) and outlet ports (B), with the seal including a valve closure member (4) operated by means of a control fluid fed through a control port (C) in the valve body. In operation a pressure differential acting to open and close the valve is set up between the inlet and outlet ports and the control port to operate the valve. This design results in cost savings and performance benefits compared with the prior art.

    Abstract: A system for hydraulically managing fluid pressure in a fluid distribution system between pressure set points includes a main valve having a fluid inlet and outlet. The main valve is configured to open to increase fluid flow therethrough and to close to reduce the fluid flow therethrough. A variable orifice assembly is coupled to the main valve and has fluid apertures formed in a housing thereof to create a fluid flow pathway therebetween. A valve stem is variably positioned within the housing to alter the fluid flow between the fluid apertures. A first control pilot is in fluid communication with the main valve and a first fluid aperture of the variable orifice assembly. A second control pilot is in fluid communication with the main valve and a second fluid aperture of the variable orifice assembly. The valve position and fluid flow are variable as the main valve opens and closes.
