| 20090277519 | METHOD AND APPARATUS FOR CONTROLLING FLUID FLOW RATE CHARACTERISTICS OF A VALVE ASSEMBLY A valve assembly controller is configured with a table having a set of command signal values representing commanded positions of a valve element to obtain a desired flow rates through a fluid pathway. The table also includes a set of empirically measured drive signal va... | 11/12/2009 |
| 20090133767 | DUAL REDUNDANT SERVOVALVE A servovalve includes a single motor which actuates separate valve members of separate servovalve assemblies. Each of the valve members controls the flow of hydraulic fluid from separate hydraulic fluid sources. In order to provide each valve member with the ability to ... | 05/28/2009 |
| 20090050222 | Three-way poppet valve with intermediate pilot port An integrated three-way poppet valve is disclosed with an intermediate pilot port and an integral load holding check valve. The valve incorporates a reverse flow check poppet for load hold capability, which enables a lower cost solution compared to a combination of valv... | 02/26/2009 |
| 20080289707 | SPOOL VALVE AND METHOD A valve (200) for routing a fluid includes a housing (220) having an inlet (222) and at least one outlet port (224). A valve member (218) is located in the housing (220). The valve (218) member has a wall (232) enc... | 11/27/2008 |
| 20080258090 | Solenoid operated fluid control valve Solenoid operated fluid control valve for a cam phasing mechanism of an internal combustion engine includes first and second control ports, a 2-stage hydraulically pilot-actuated, pressure balanced spool having an integral control feedback passage and a linear force sol... | 10/23/2008 |
| 20080202608 | Hydraulic valve with spool position sensing assembly A hydraulic valve includes a valve body, a valve spool that is movable relative to the valve body for controlling fluid flow through the valve body, and a spool return assembly for biasing the valve spool into a centered position relative to the valve body. The hydrauli... | 08/28/2008 |
| 20080196777 | Electromagnetic Hydraulic Valve An electromagnetic hydraulic valve (1) is provided having a magnetic armature (8) which is guided in a longitudinally movable fashion in an armature guide (9) and activates a valve push rod (15) which extends in a valve housing (14). T... | 08/21/2008 |
