Abstract
A fluid power operate linear drive possessing a slab housing (2) with an elongated cross sectional outline, in which a plurality of receiving spaces (8) are arranged extending in a common housing plane adjacent to each other in the direction of the longitudinal axis (3) of the cross section. At one first narrow side (21) of the housing there is a piston receiving space (12) extending in the longitudinal direction containing a piston (13) connected with an outwardly running force output part (16). At the opposite second narrow housing side (22) there is an electronic circuitry receiving space (23) containing electronic valve control circuitry (24). Between the piston receiving space (12) and the electronic circuitry receiving space (23) there is at least one valve receiving space (26), which contains a control valve means (25), which is able to be electronically operated and serves for the control of fluid actuation of the piston (13).
