|---|
| 251048000 | Dashpot or fluid controlled retarder or timer | 6 |
| 20110226973 | LIFT ASSIST AND DAMPER ARRANGEMENT - A lockable lift assist assembly includes a piston assembly moveable between an extended position and a retracted position. A valve assembly is coupled in movement together with the piston assembly. The valve assembly is configured to selectively alter a flow of a hydraulic fluid through a fluid communication path established within the valve assembly to control movement of the piston assembly. | 09-22-2011 |
| 20120061594 | Volume Booster with Stabilized Trim - A fluid flow control device includes a body having an inlet connection, an outlet connection, and a discharge port. A supply path extends between the inlet connection and the outlet connection and a booster module is disposed within the body. The booster module includes a control element and an actuator element and defines an exhaust path extending between the outlet connection and the discharge port. A supply port is disposed within the booster module along the supply path between the inlet connection and the outlet connection and at least a first damping means operatively connected to the booster module. | 03-15-2012 |
| 20120199766 | Solenoid operated fluid control valve - Solenoid operated fluid control valve for controlling the pressure of a fluid in a fluid control system comprises a solenoid housing having therein a solenoid coil, an armature movable in response to electrical current applied to the solenoid coil, a valve member for controlling fluid flow to a fluid passage, an actuator pin disposed between the armature and the valve member for moving the valve member in response to armature movement, and one or more features including an armature damping member, tubular actuator pin support body, flow diverter, coil bobbin support sleeve, and/or internal particle gettering magnet to improve valve operation. | 08-09-2012 |
| 20150048265 | HYDRAULIC COUPLING - A hydraulic coupling is specified, particularly for fuel injectors, which has a housing pot having a pot bottom and a lateral pot surface, a piston guided axially displaceably in the housing pot, a fluid-filled coupling gap that is provided between the piston and the pot bottom, diaphragm situated on the outer side of the housing pot facing away from the piston, a compensation chamber that is bordered by the diaphragm and flow-connected to the coupling gap, and a spring element acting upon the diaphragm with an axially directed spring force. In order to achieve a low overall stiffness of the hydraulic coupling at the required specified coupling force, the spring element is developed as a spring bracket fixed to the housing pot, which lies against the diaphragm with axial prestressing in the region of the pot bottom. | 02-19-2015 |
| 251050000 | Line pressure connected dashpot or choke chamber | 1 |
| 20090261278 | Apparatus for Controlling Fluid Flow - An apparatus for controlling fluid flow comprising a main chamber having an inlet and an outlet, a control member movable between a start position where the outlet is open and a finish position where the outlet is at least partially closed, an urging means for urging the control member to the start position and trickle means for allowing a trickle of fluid to exit the outlet when the control member is in the finish position. | 10-22-2009 |
| 251054000 | Closed fluid circuit dashpot or choke chamber | 1 |
| 20150076376 | Adjustable Damping Valve Arrangement - An adjustable damping valve arrangement for a vibration damper includes a main stage valve with a main stage valve body which is guided in a damping valve housing so as to be axially movable. 6 The damping valve housing has a housing insert which is separate from the damping valve housing and in which the main stage valve body is guided. | 03-19-2015 |
