| 092051000 | MUTUALLY RELATIVELY MOVABLE CYLINDER OR SLEEVE, MEMBER SEALINGLY SLIDABLE THEREIN AND OUTER CYLINDER THEREFOR | 7 |
| 20090173221 | FLUID POWER LINEAR DRIVE DEVICE - A fluid power linear drive device comprises a housing tube on whose outer periphery an output drive slide can slide linearly. For this purpose on the outer periphery of the housing tube there are two guide face pairs each having two guide faces extending along the housing tube on the outer periphery of the housing and, in the axial is direction of a first transverse axis of the housing tube, opposite each other, which in the direction of a second transverse axis, perpendicular to the first transverse axis, are spaced apart. The guide faces, as considered in a cross section of the housing tube, are slanted in each case in relation to the first and second transverse axis, first bearing elements arranged on the output drive slide are engaging the guide faces of the one, first guide face pair, such first bearing elements being able to pivot in relation to a pivot axis extending in the longitudinal direction of the housing tube independently of each other in relation to the output drive slide, and the guide faces of the other, second guide face pair are engaged by second bearing elements arranged of the output drive slide, the transverse position of the second bearing elements assumed in the axial direction of the first transverse axis in relation to the output drive slide being able to be varied. | 07-09-2009 |
| 20130205989 | Axial Piston Machine having a Retraction Plate, and Method for the Production Thereof - An axial piston machine comprises a cylinder drum in which a multiplicity of pistons are arranged in a longitudinally displaceable manner. The pistons are supported, via sliding blocks, on a running surface which is inclined relative to the cylinder drum axis. The sliding blocks are held, at that side thereof which faces away from the running surface, by means of a retraction plate. The retraction plate is produced from processed sheet metal in a non-cutting punching and stamping process. | 08-15-2013 |
| 20140157978 | AIR SHOCK ABSORBER AND STRADDLE-TYPE VEHICLE - An air shock absorber includes seal members that maintain the sealing performance and slidability of the seal members. The air shock absorber includes a cylinder and a piston. The cylinder contains gases and is divided by the piston into a high pressure gas chamber and a low pressure gas chamber. A first seal member extends in a circumferential direction of the piston along its outer periphery. A second seal member is located on the outer periphery of the piston closer to the high pressure gas chamber than the first seal member is. A surface of the first seal member includes a groove. A surface of the second seal member faces the surface of the first seal member and includes a groove. | 06-12-2014 |
| 20160096617 | HYDRAULIC ACTUATOR - A hydraulic actuator is adapted to drive a spoiler of a wing having a flap. When the hydraulic actuator drives the spoiler in an overlapping region where a driving range of the flap and a driving range of the spoiler overlap, an output suppressing structure suppress a drive output of the hydraulic actuator in the overlapping region to be less than that in a non-overlapping region other than the overlapping region. | 04-07-2016 |
| 092052000 | Cylinder or sleeve forms working member | 1 |
| 20120186442 | Double Cylinder Type Hydraulic Mechanism - A hydraulic mechanism includes an outer cylinder having an expansion side working port and a contraction side working port respectively formed on a top of the outer cylinder; an inner cylinder insertedly installed inside the outer cylinder to come in and out toward a bottom of the outer cylinder; an inner rod having two flow paths respectively connected to the expansion side working port and the contraction side working port, one end of which is fixed to an inner top surface of the outer cylinder, and the other end of which passes through a top of the inner cylinder and protrudes to be positioned inside the inner cylinder; and a piston combined with the other end of the inner rod to be positioned inside the inner cylinder and formed with a hole connected to the flow path of the inner rod connected to the expansion side working port. | 07-26-2012 |
| 092053000 | With additional cylinder relatively slidable exteriorly of outer cylinder | 2 |
| 20100307331 | TELESCOPIC COMPOSITE CYLINDER HYDRAULIC HOIST - The present invention is a telescopic composite cylinder that functions as a hydraulic hoist incorporating multiple cylinders formed of composite materials. The walls of the multiple cylinders may be formed of pultruded composite material, or a combination of composite materials. The cylinders of the hydraulic hoist may incorporate a plurality of piston and sleeve assemblies that are mounted so as to invoke a telescopic relationship between the multiple cylinders. The materials that the cylinders are formed of may create walls having a smooth surface that can eliminate problems facing hoists formed of other materials, for example, such as a honing process, fluid leakage and seal wearing problems. The hoist may be run on diesel fuel drawn from the tank of a vehicle. Additionally, the present invention may be releseably attached to a surface by way of a saddle mounting system. | 12-09-2010 |
| 20130098238 | OIL-GAS SEPARATED PRESSURE CYLINDER - An oil-gas separated pressure cylinder, which combines a hydraulic cylinder, a pneumatic cylinder and a pres-pressure cylinder, and keeps the applied compressed gas and the storage hydraulic fluid apart, maintaining the quality of the hydraulic fluid and saving the hydraulic fluid replacement cost. When the applied compressed gas enters the pre-pressure cylinder to move a pre-pressure cylinder piston in forcing the storage hydraulic fluid out of an oil storage space of the pre-pressure cylinder into an oil storage space in the hydraulic cylinder, a hydraulic cylinder piston of the hydraulic cylinder is then forced by the hydraulic fluid to move a hydraulic cylinder piston rod against the workpiece, and then a pneumatic cylinder piston rod of the pneumatic cylinder is forced into the oil storage space of the hydraulic cylinder to enhance the pressure at the hydraulic cylinder piston rod against the workpiece. | 04-25-2013 |
