188322220 | Thrust member or piston structure | 7 |
20090194379 | Fluid-pressure shock absorber - A fluid-pressure shock absorber comprising: an external cylinder with an open portion provided at one end thereof, a piston rod, a tip of which projects from the open portion of the external cylinder; a rod guide, wherein the open portion of the external cylinder is closed with caulking works so as to make a caulking portion, and further comprising: an annular bump cap coaxially arranged relative to the external cylinder; a cap holder arranged on a side of the tip of the piston rod relative to the rod guide so as to retain the bump cap, wherein an end portion on the rod guide side of the bump cap is abutted to the caulking portion, and a clearance in an axial direction is formed between an end portion of the cap holder on a side towards the tip of the piston rod and the bump cap. | 08-06-2009 |
20090229935 | Continuously Blockable Locking Device - A housing having a first housing end and a second housing end, a substantially cylindrical work chamber formed in the housing, a piston which is arranged in the work chamber so as to be displaceable and which divides the work chamber into a first work space near the first housing end and a second work space near the second housing end, a piston rod which is arranged at one side of the piston and which projects through the first work space and is guided out of the work chamber in a sealed manner at the first housing end through a guiding and sealing device, and a valve chamber which is formed in the housing parallel to the work chamber and in which a first valve assembly and a second valve assembly are arranged. The work chamber is always completely filled with a liquid medium and the valve chamber is at least partially filled with a liquid medium. | 09-17-2009 |
20110290605 | Vibration Damper - A vibration damper includes a cylinder in which a piston fastened to a piston rod executes a translational and a rotational movement relative to the cylinder. The piston is fixed to the piston rod by an axial fastener, and a device for preventing rotation by positive engagement is formed between the piston and the piston rod. | 12-01-2011 |
20130043100 | DAMPING SHAFT MECHANISM - A damping shaft mechanism has a spiral shaft, spiral guide bush, a shell and blade. An external spiral structure is arranged at one end of the spiral shaft, and its core has a cone segment. An internal spiral structure is arranged in the spiral guide bush, which cooperates rotationally with the external spiral structure so that it can move along the axis relative to the spiral shaft when the spiral shaft is rotating. The two cavities change size by moving the spiral guide bush driven by the spiral shaft in the shell, and the taper on the spiral shaft makes the fit clearance between the spiral shaft and the spiral guide bush changed from maximum to minimum gradually in the damping process, so that the oil-flowing section between the two cavities changes from big to small. | 02-21-2013 |
20130168195 | PISTON ASSEMBLY OF SHOCK ABSORBER - Disclosed herein is a piston assembly of a shock absorber which ensures easy and prompt connection of components in the correct positions in assembling the piston assembly of a shock absorber by forming a seating unit between a piston body and a compression retainer and between the piston body and a tension retainer. | 07-04-2013 |
20130333993 | PISTON ASSEMBLY OF SHOCK ABSORBER - A piston assembly of a shock absorber is provided. A compression retainer and a rebound retainer are disposed above and under a piston body. A blow-off reducing unit is disposed between the compression retainer and an auxiliary valve and on a bottom surface of the auxiliary valve to form a plurality of blow-off points, so that a rapid variation in a damping force can be considerably reduced even in a low-speed and middle-speed transition period. | 12-19-2013 |
20140027220 | Separating Piston - A separating piston for hydropneumatic units, separating a cylinder interior which is filled with liquid in a cylinder from a gas-filled compensation chamber or spring space in a sealing manner and which is formed of two parts and has a radially circumferential seal groove in which is arranged an annular seal which can tightly contact the inner wall of the cylinder. One of the two separating piston parts is a guide part which has characteristics conducive to sliding and which slides at the inner wall of the cylinder, and the other separating piston part is a retaining part which is connected to the guide part. The guide part is a stamped and/or bent sheet metal part which is coated with a guide or running layer at least on its guide area sliding along the inner wall of the cylinder. | 01-30-2014 |
