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, the 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. The 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 part (128) for locking the abutment part (114).

Abstract: A linear drive comprising a drive member adapted to be reciprocated axially in a housing between two end positions. Opposite to the former there is a wall on at least one axial side. There are means to reduce the impact in the end position, such means having an annular lip. The lip is arranged on the drive member or on the wall and respectively faces the wall or the housing. The lip defines a damping space which is open on an impact side. If the drive member approaches one end position thereof, the damping space is occluded and reduced in volume so that some trapped fluid will escape via a relief opening so that there is a braked part of the stroke. Using simple means it is therefore possible to provide an extremely efficient fluid damping at the end position.

Abstract: An improved cylinder structure for a pneumatically operated tool, which is characterized in the two air tight chambers defined at the front and rear ends of the cylinder so that the air confined therein can produce reaction pressure respectively to reduce the operation speed of the piston when it approaches the dead ends of the cylinder and further to bounce back the same in a rapid manner whereby the impact of the moving piston can be effectively reduced at the dead ends and the noise and vibration generated as a result of high speed impact on the ends of the cylinder can also be minimized; moreover, the piston can be protected from being deformed and damaged due to constant direct impacts.

Abstract: A fluid jack (10) has a cushioning device (21) positioned within a cylinder (11) between a piston means (12) and a closed end (13) with the cushioning device (21) being a self-contained unit independent of any major components of the fluid jack (10). A variable volume chamber (24) is formed between a pair of members (22,23) with the cushioning taking place by metering the fluid expelled from the variable volume chamber (24) in response to the piston means (12) engaging and moving one of the members (22,23) in a direction for decreasing the volume of the variable volume chamber (24).

Abstract: Cushioning apparatus for cushioning a hydraulic jack is disclosed which includes a plunger reciprocably mounted within a blind bore. The plunger sequentially closes off a plurality of axially spaced orifices provided through the wall of the bore as the plunger moves from a first position adjacent the open end of the bore to a second position adjacent its closed end, thereby progressively restricting the escape of fluid from the bore so as to slow the movement of one of the telescopic members of the jack toward another.
