Abstract

In such a piston/cylinder unit (1) which serves to drive an elevator car (3), the cylinder (7) is mounted in the foundation on a support (8) which at the same time constitutes the cooler for the hydraulic fluid. The feed and discharge of the hydraulic fluid to and from the cylinder (7) is effected here via the support (8), which is constructed as a hollow cylinder and has cooling ribs (9) on its outer surface. The hydraulic fluid heated during the work cycle can be recooled via these ribs instead of a separate cooler, which is usually difficult to accommodate.
