Problems solved by technology

[0004] Both known linear drives require a certain manufacturing outlay due to the integrated travel presetting possibility, which is reflected in the production costs
In the case of applications in particular which do not require a stroke adjustment, the linear drive is basically designed with a functional margin (überdimensioniert) and entails costs on the part of the user for measures not actually required by the user

Embodiment Construction

[0036] Preferably, the fluid-actuated linear drive, designated as a whole with the reference numeral 1, is designed for actuation by means of compressed air as drive fluid, but is also suitable for actuation by means of other gaseous or also liquid drive fluids. .

[0037] The linear drive 1 has a drive housing 2 that preferably has a longitudinal profile. The driver housing 2 has a longitudinal axis 3 defining a housing longitudinal direction 3 , a transverse axis 4 at right angles thereto defining a housing transverse direction 4 , and a vertical axis 5 at right angles to the longitudinal axis 3 and the transverse axis 4 ( It delimits the housing height direction 5). Preferably, the drive housing 2 is designed in the shape of a plate or a table.

[0038] The driver housing 2 has a housing rear side 6 oriented in the housing longitudinal direction 3 and a housing front side 7 axially opposite thereto. Furthermore, the drive housing 2 has a housing top side 8 oriented in th...

Abstract

A fluid actuated linear drive includes a drive housing and a drive member which is movable between two stroke end positions. The drive member has a drive unit with a drive piston which divides off two drive chambers from one another, the drive chambers via two housing channels being connected to axial housing coupling openings which are arranged on a housing rear side. A multi-function module is built onto the housing rear side in a position of use and includes components of an external end position setting device for the drive member and is furthermore provided with module block channel systems which communicate with the housing channels and can be used for the feed and discharge of a drive fluid when the multifunction module is built onto the drive housing in the position of use.

Description

technical field [0001] The invention relates to a fluid-operated linear drive, which has a drive housing and a drive link that can be driven by fluid force to perform a linear stroke movement relative to the drive housing along the longitudinal direction of the housing, wherein the drive link has a drive unit. The drive unit has a drive piston, which in the drive housing separates two drive chambers that follow one another in the longitudinal direction of the housing from each other, the drive chambers being respectively connected to two shells that pass through the drive housing. One connection in the body channel, which exits at the housing rear side of the drive housing at the housing rear side of the drive housing with a dedicated axial housing connection opening at the housing rear side of the drive housing oriented in the housing longitudinal direction It can also be used to supply and discharge a drive fluid that produces a linear stroke movement, wherein the drive elem...
