Abstract: A hydraulic cylinder for a hydraulic clutch actuating system for motor vehicles has a piston subassembly with a piston and piston rod, a cylinder housing in which a pressure chamber is variably bounded at one side by the piston and fixedly bounded at the other side by a base of the cylinder housing. A spring element is arranged at the side of the piston opposite from the pressure chamber and is supported at one end on a spring plate on the housing side and operatively connected at the other end with the piston rod so as to bias the piston subassembly in a direction away from the base. A fixing section fixes the piston subassembly in a predetermined stroke setting with respect to the cylinder housing prior to first actuation of the hydraulic cylinder and is constructed to release the piston subassembly relative to the cylinder housing upon first actuation.

Abstract: A linear actuator having a power rod supported by movable supports is disclosed. The movable supports can provide support to the power rod to avoid buckling of the power rod under large compressive forces. The movable supports are designed to move towards (e.g., by a biasing mechanism) a first position that minimizes the unsupported length of the power rod, but are capable of being displaced by the power rod during extension of the power rod. Examples of movable supports include slidable bearings (e.g., axially slidable) or rotating braces (e.g., rotatable form a supporting position to an out-of-the-way position). Examples of suitable biasing mechanisms include springs and spring members. In some embodiments, hydraulic force is used to move the movable supports.

Abstract: A hydraulic cylinder has a cylinder housing in which is formed a pressure chamber variably bounded on one side by a piston of a piston subassembly that is longitudinally displaceable. A piston rod is rigidly connected with the piston, wherein the piston has an outer contour, which permits tilting of the piston subassembly in the cylinder housing, and a projection, which is at the pressure chamber side and on which a sealing element is centered and retained by a retaining ring. The sealing element has an encircling sealing lip that slidably and sealably bears against a sliding surface of the cylinder housing. The retaining ring is provided on the side thereof opposite from the sealing element with a stiffened prolongation.

Abstract: A linear actuator includes a guide mechanism and a retainer. On a guide block of the guide mechanism, a pair of ball-circulating grooves is formed on the lower surface that faces a cylinder body. Multiple balls are loaded in the ball-circulating grooves. Paired cover blocks are respectively mounted on the two ends of the guide block. The retainer has the form of paired ball clips, which are formed as arms to engage with the cover blocks when the clips are inserted in the ball-circulating grooves to hold the balls. Paired cover plates are respectively mounted on the end faces of the cover blocks, and arm-shaped cover clips are mounted so as to hold the cover plates. The cover plates, the cover blocks, and the guide block are thereby integrally linked.

Abstract: A fluid pressure cylinder includes a displacement member, which is displaceable on an end side of a body, and a connecting body, which is connected to a piston rod of a cylinder unit, is inserted via a spring in a block body of the displacement member. A suction rod is connected substantially in parallel with the connecting body and a buffer rod connected to the connecting body. In addition, in a state where downward displacement of the block body is restricted, when additional loads are applied, the buffer rod is displaced relatively with respect to the block body in opposition to an elastic force of the spring, whereby an interval in a radial direction between a bushing and the buffer rod is enlarged.

Abstract: A cylinder body includes a first guide surface made up from first guide grooves and a first bulging portion, wherein a slide table is displaceably supported on the first guide surface via a guide mechanism. Additionally, guide members of a guide block that constitutes the guide mechanism are inserted into and fixed within the first guide grooves. Further, the cylinder body is equipped with a second guide surface, which is formed with substantially the same shape as the first guide surface. In the event that the first guide surface is oriented upwardly and the slide table is installed thereon, the second guide surface acts as a mounting surface, whereas, in the event that the second guide surface is oriented upwardly and the slide table is installed thereon, the first guide surface acts as the mounting surface.

Abstract: A piston, which is provided in a cylinder tube, is connected to a pair of guide rods by the aid of a plate. The guide rods are arranged displaceably in the axial direction along guide holes of the cylinder tube. The displacement of the piston is guided by the guide rods. The guide holes are communicated with the outside via a tube connected to an air hole. The air is sucked into and discharged from the guide holes via the tube in accordance with the reciprocating motion of the piston.
