Embodiment Construction

[0028] The linear actuator marked 1 as a whole is driven by fluid power, and the driving medium may be a liquid medium or a gaseous medium. The medium is preferably compressed air.

[0029] The linear drive 1 has an elongated housing 2 with a front end wall 3 and a rear end wall 4 and a tubular peripheral wall 5 extending axially between them. Preferably, the housing 2 is cylindrical as a whole and in particular cylindrical.

[0030] Inside the housing there is a piston 7 which slides linearly in the direction of the longitudinal axis 6 of the housing 2 , which is kinematically coupled with a drive output 8 accessible from the outside of the housing 2 . The output drive part 8 is preferably a piston rod 8a which extends through the front abutment wall 3 in the outward direction and whose part on the outside of the housing 2 is provided with a male thread 12 or some other attachment mechanism on which Detachably fastens a component (eg, part of a machine) to be displaced or p...

Abstract

The linear drive has a housing defining a tubular peripheral wall extending between front-sided connection walls (3). One of the connection walls is formed by a base wall (27) of an end cap (24). The cap encloses an axially immovably fixed expansion element, where the element carries an axially upstream collision surface for a piston at a front side of the connection wall. A tube section (26) axially overlaps the element without axially supporting a radially outward piece, where the element is fixed at the housing in an area lying axially behind a front side of the element.

Description

technical field [0001] The invention relates to a fluid-operated linear actuator comprising a housing for a linearly movable piston in the form of two terminal terminating walls and a tubular peripheral wall, at least one of which is defined by the bottom wall of the terminating cover Formed, the side wall of the terminal cover defines one length portion of the peripheral wall and it is adjacent to the tubular element defining the other length portion of the peripheral wall, the terminal cover surrounds the filling body, and the filling body internally rests on its side wall and against its On the bottom wall, the packing body is fastened axially immovably with respect to the terminating cover, the packing body exhibiting on its front side an abutment face for the piston, which is located axially in front of the terminating wall. Background technique [0002] In the case of a known fluid-operated linear actuator of this type disclosed in European Patent Publication No. EP 08...
