Abstract (en)
[origin: EP0269905A2] The lifting cylinder unit consists of a cylinder (10) and a head part guided directly on it. The cylinder (10) has a longitudinal bore (18) in which a piston (20) slides which can be pressurized pneumatically or hydraulically on either side. The piston is connected to the head part via a piston rod (26). The cylinder and the head part are roughly the same length, the head part (12) being guided on the cylinder (10) like a slide on a bed. This results in a very compact type of construction. In order to further reduce the space requirement, the pressure connections (32, 36) are attached to the same end (14) of the cylinder (10). A passage (30) leads from one pressure connection (32) to the opposite end (16) of the cylinder (10). The passage (30) is formed by a longitudinal groove which is made in the longitudinal bore of the cylinder (10) and, except for an orifice (34), is closed off radially to the inside by a bush (28) which lines the longitudinal bore. <IMAGE>
