| 137625420 | Selective opening of plural ports | 10 |
| 20100236652 | VALVE UNIT - A valve unit | 09-23-2010 |
| 20100269935 | VALVE SYSTEM - The invention relates to a valve arrangement with a continuously variable directional control valve, wherein the valve slide thereof can be adjusted in the direction of five positions in order to control a user in two directions, to carry out a quick motion, to switch into a floating position or to close off the pressure means connection to the user (neutral position). | 10-28-2010 |
| 20110232789 | THREE-WAY CONTROLLABLE VALVE - A valve system includes a conical valve body disposed in an engine gaseous fluid stream and having a first fluid passageway, where the conical valve body is a cone or a frustum of a cone. The system includes a fluid inlet conduit fluidly coupled to the conical valve body on an upstream side, a first fluid outlet conduit, and a second fluid outlet conduit. The first and second fluid outlet conduits are fluidly coupled to the conical valve body on a downstream side. The valve system includes a valve actuator operatively coupled to the conical valve body and that rotates the conical valve body, and a controller that provides a valve actuator command and thereby selectively flows the engine gaseous fluid stream through the first fluid outlet conduit and the second fluid outlet conduit. | 09-29-2011 |
| 20110232790 | Rotary Supply Joint, Rotary Timing Valve And Product Handling Apparatus - A rotary supply joint that may, in particular be a rotary timing valve, is provided for providing fluid flow at least periodically from inlet ports to outlet ports when respective openings in first and second surfaces which are rotating relative to each other are aligned, in which a gas bearing is arranged to provide a bearing force between the first and second surfaces. | 09-29-2011 |
| 20130061966 | MAGNETIC CONTROL MULTI-WAY VALVE - A magnetic control multi-way valve has a fixed unit, at least two control valves and a second magnet. The fixed unit is provided with a inlet and at least two independent mounting cavities, an outlet is formed at the lower port of the mounting cavity; two control valves are mounted in the mounting cavities respectively; and the control valve comprises a spool assembly, a first magnet, a sealing gasket, a first spring and a second spring. The spool assembly is fixedly arranged in the mounting cavity with a pressure relief way; the first magnet which is connected in the mounting cavity in an up and down sliding manner and is above the spool assembly; the sealing gasket is connected in the mounting cavity in a vertical sliding manner and is below the spool assembly; the second magnet is connected out of the fixed unit in a horizontal sliding manner. | 03-14-2013 |
| 20130263953 | VALVE ASSEMBLY - A valve assembly ( | 10-10-2013 |
| 20140174575 | WHEATSTONE BRIDGE CHECK VALVE ARRANGEMENT - A device is disclosed that may include a spool valve having a first connector and a second connector and a spool movable for controlling flow between the first connector and the second connector, regardless of direction of flow through the spool valve. A pilot valve having an inlet and an outlet develops a command pressure. A feedback circuit having an inlet and an outlet develops a feedback pressure. The spool valve may be responsive to the command pressure and the feedback pressure. A fluid rectifier circuit is provided to connect the higher pressure of the first connector and second connector to the pilot valve inlet and feedback circuit inlet, and connect the other of the first connector and second connector to the pilot valve outlet and feedback circuit outlet. | 06-26-2014 |
| 20140352826 | DIRECTIONAL POPPET VALVE - The invention relates to a directional poppet valve ( | 12-04-2014 |
| 20150300213 | HYDRAULIC VALVE FOR CAM PHASER - A hydraulic valve, in particular for a cam phaser of a cam shaft, the hydraulic valve including a supply connection with a check valve for supplying a hydraulic fluid; at least one first operating connection and a second operating connection; at least one first tank outlet and a second tank outlet for draining the hydraulic fluid; a piston that is moveable in a bore hole along a longitudinal direction of the bore hole for distributing the hydraulic fluid from the supply connection to the first operating connection and/or the second operating connection and for conducting the hydraulic fluid from the first operating connection to the second operating connection and from the first operating connection to the first tank outlet and/or from the second operating connection to the second tank outlet; and a sleeve that is arranged in the piston moveable relative to the piston in the longitudinal direction. | 10-22-2015 |
| 20160033052 | SERVO VALVE WITH DOUBLE MOBILE ASSEMBLY - Hydraulic servo valve ( | 02-04-2016 |
