| 20160123495 | LEVER TYPE SWITCH VALVE - A lever type switch valve has a switch chamber with three sections in the axial direction including, two outlet cavities at two ends and an inlet cavity in the central section. The outer end of each outlet cavity in the axial direction has a slide section; an inner protruding ring is disposed between two ends of the inlet cavity and the outlet cavities; a spindle of dumbbell shape, the spindle is slidably coupled to the inner side of the switch chamber axially; the spindle has three sections in the axial direction that are two pistons at two ends and a flowing section in the central section; the piston has a big outer end and a small inner end. The outer ends of the pistons are slidably coupled to the slide section in sealing way, the axial length of the outlet cavity is larger than the axial direction of the piston. | 05-05-2016 |
| 20160130787 | FLOW RATE CONTROL VALVE FOR CONSTRUCTION MACHINE - Disclosed is a flow rate control valve for a construction machine. A flow rate control valve for a construction machine comprises: a valve body having a pump channel for receiving operating oil from a hydraulic pump, a supply channel connected to the pump channel, and an actuator port connected to a hydraulic actuator; a spool installed inside the valve body to be switchable such that, when switched in response to application of signal pressure, the spool selectively causes the supply channel and the actuator port to communicate with each other; a tank channel installed inside the valve body and connected to an operating oil tank; and an orifice formed in the spool to have an inlet formed on an end and an outlet communicating with the tank channel, wherein, when the spool is initially actuated, a part of the signal pressure is discharged to the operating oil tank via the orifice. | 05-12-2016 |
| 20160131270 | Valve - A valve includes at least one seal ring arranged in a recess of a valve housing, which seal ring has a seal housing having a U-shaped cross-section, in which an annular sealing element is arranged. At least one of the two housing legs of the seal housing is designed as a guiding leg, which effects transverse support and linear displacement guidance of a valve slide that passes through the seal ring. | 05-12-2016 |

| 20160146367 | SOLENOID VALVE - A solenoid valve is provided which can be reduced in size while allowing a plunger and a shaft to slide smoothly. A solenoid valve includes a solenoid portion with a plunger that moves in an axial direction using a magnetic force generated by a solenoid coil. The solenoid portion has a cover member that houses the plunger, a shaft that is movable in the axial direction along with the plunger, and a core member that attracts the plunger in the axial direction. The shaft is supported by a first bearing portion formed on a cylindrical portion of the core member and a second bearing portion formed on a second bottom portion of the cover member such that the shaft is movable in the axial direction. | 05-26-2016 |

| 20080223466 | PILOT-OPERATED THREE-PORT VALVE - A pilot-operated three-port valve includes three ports, two valve seats that are concentric and opposite each other, a poppet-type valve member that is disposed between these two valve seats, and a pilot operating portion that opens and closes the valve member using a rod. Seat surfaces of the two valve seats and a first seal surface and a second seal surface of the valve member are flat. The valve member is attached to an end of the rod coaxially with the rod and so as to have a degree of freedom of inclination from the axis of the rod. | 09-18-2008 |
| 20110290357 | Valve for a Pneumatic Hand Tool - A valve body has a channel extending along an axis and an inlet port open to the channel. A sleeve, received about the valve body, overlies the inlet port and is rotatable about the axis relative the body. A nozzle projects radially outward from the sleeve. The nozzle is rotatable with the sleeve into a range of positions in which the nozzle communicates with the inlet port through the sleeve. | 12-01-2011 |
| 20160123480 | Device for controlling fluid media and use of a molded part in such a device - A device for controlling fluid media, such as a directional control valve, includes a molded part made from an elastomeric material in which at least one line section is formed. The line section connects at least two connections to one another, between which at least one flow path extends. The device or valve has a control unit that includes an actuator coupled to at least one blocking element. The at least one blocking element is displaced by the actuator between a blocking position and a release position. In the blocking position, the at least one blocking element deforms the at least one line section in order to block the at least one flow path. | 05-05-2016 |
