Abstract
Improvements in hydraulic lifts, with a base plate on which a pump cylinder is fixed, a lift cylinder and a tank that concentrically surrounds the latter, which is in communication with the pump cylinder through a first passage that passes through the base plate and a first check valve that makes it possible during the pumping to release a hydraulic medium from the tank, the pump cylinder being in communication with the lifting cylinder, through a second passage that passes through the base plate and a second check valve that enables the hydraulic medium to exit the pump cylinder during pumping, the lifting cylinder being in communication with the tank through a discharge passage and an organ lock featuring an adjustable bolt, and with the adjustable bolt being guided in a lock hole in the base plate, which It has an area configured as a closing seat and two areas on both sides of the latter, one of the latter two areas being in communication with the tank through a first communication hole, and the other in communication with the lifting through a second communication hole, and ascending the closing hole towards the edge of the base plate, characterized in that the base plate is a laminated plate (1), substantially flat, which presents in the area of the area outer end (17a) of the closing hole (17) a bulge (1f) produced by shaping that extends approximately to the outer wall (2b) of the tank (2d), with the laminated material in the area of the bulge (1f) substantially the same thickness as in the remaining area of the base plate (1) (Machine-translation by Google Translate, not legally binding)
