    Abstract: An actuator includes a ram structure slidably mounted within a cylinder structure bore and defines with the cylinder structure a gap therebetween. A fluid passageway structure in the ram structure defines a path for fluid to flow through the ram structure and includes an outlet in a sidewall of the ram structure. A cushioning seal located between the ram structure and the cylinder structure can engage the ram structure and a cylinder cap during ram structure extension such that the seal substantially closes off a first portion of the gap extending from the seal toward an open end of the cylinder structure. The cushioning seal can move during ram structure retraction in a direction of ram structure retraction such that fluid flowing out of the ram structure sidewall outlet, when the outlet is in the gap first portion, flows between the seal and the cylinder cap.

    Abstract: A linear actuator provided for moving a load includes an actuator housing having a tube and a housing bottom at one end of the tube and a housing head at another end of the tube. The linear actuator further includes a piston guided longitudinally in the actuator housing, and an actuator rod assembled with the piston and configured to protrude out of the actuator housing in a manner which is guided in the housing head. The linear actuator is configured such that reliability of operation is increased and damage of structural parts is largely avoided. The linear actuator achieves these results by virtue of the fact that there is at least one plastically deformable buffer element which can be supported on the housing head and can be deformed in the case of an impact of the piston. The buffer element is configured to convert kinetic energy into deformation work.

    Abstract: Provided is a hybrid servo actuator for a crash test, and more particularly, a hybrid servo actuator for a crash test in which an operating part including a piston and a rod, a chamber supplying an air pressure to the operating part, and a controller controlling a movement of the operating part are integrally formed, thereby increasing a moving speed in a stroke direction of the operating part more than in a general hydraulic cylinder and pneumatic cylinder. The actuator includes an oil pressure cushion type cushion part provided therein to absorb a shock generated by a shock of an operating part even at the time of a malfunction of the operating part and discharge an oil pressure generated by the shock to the outside and thus is used semi-permanently.

    Abstract: The invention relates to a rotating or pivoting device (110) comprising a housing (12), at least one working piston (14) which is mounted in the housing and subjected to a pressure medium, and a pivoting part (20) which is rotatably mounted in the housing and is rotatably driven by the working piston by means of a rotating coupling mechanism, said working piston being mounted in the housing in such a way that it can be displaced in a housing-side cylinder, The inventive rotating or pivoting device also comprises an abutment part (114) that limits the stroke of the working cylinder in at least two positions and can be locked at least in its axially inner intermediate position. Said abutment part is provided with a locking piston (120) that is mounted in such a way that it can be axially displaced, and, when the abutment part is in its intermediate position, can be displaced against a spring element (122) in a pressurised manner into a locking position, and, in the locking position, activates locking means (128) for locking the abutment part (114).

    Abstract: High frequency shock absorber/accelerator built in at any or both end of conventional air cylinder that includes piston moving axially inside cylinder body and sealed against inner surface of body by sealing structure. Cylinder piston rod protrudes outside thru cylinder front-end block Shock absorber/accelerator comprises piston with sealing structures moving axially in inner chamber, which communicates with outer chamber thru aperture(s). Air cylinder piston meets the protruded rod of the shock absorber/accelerator piston and starts to move it thus pushing volume of compressed air through provided aperture from inner chamber to outer chamber. Piston sealing structures seal air coming through the aperture thereby isolating compressed air in the outer chamber from the inner chamber. Compressed air coming through the open venting valve forces pistons to move in opposite direction. Then, shock absorber/accelerator aperture opens and compressed air rushes back from the outer to the inner chamber for powerful acceleration.

    Abstract: A shock absorbing hydraulic actuator comprises a cylinder with first and second pistons slidably disposed therein. The first and second pistons are moveable relative to each other. A poppet is supported by the first piston and is moveable relative to the first piston. In response to hydraulic fluid pressure within a passage of the first piston, the poppet can be caused to move in a direction which opens a passage through the first piston to allow the first piston to move relative to the second piston in response to a shock impact such as that which can result from an outboard motor striking a submerged or floating object. The second piston remains in its original position. A bleed passage allows the first piston to resume its original position next to the second piston after the impact has occurred. This movement towards its original position is caused naturally by the weight of an object supported by the hydraulic actuator, such as an outboard motor.
