Abstract

A fluid power linear drive has a drive housing (1) in which a housing chamber (4) is located containing at least one piston (5). The drive housing possesses two housing parts (2 and 3) placed alongside each other, which at mutually facing joint faces (16 and 17) are provided with half chambers (18a and 18b) constituted by elongated, groove-like recesses, which half chambers are united in a complementary fashion to form at least one housing chamber (4).
