Remote control of oil level in crank case or gear - uses simple manual pressure on button to display liquid level

摘要

The system is designed for the remote control of a liquid level in a gear case or various liquid containers for vehicles or machines. It has a cylinder rod fitted with several capillary tubes, the lower ends of which correspond to the different liquid levels to be controlled. The upper ends of the capillary tubes terminate in a cylindrical reading and control element. This element has transparent chambers whose filling or non-filling, is obtained by an instantaneous manual pressure, give a visual indication of the liquid level position in the container. The control element has a base (4) fixed on a housing (12). It has a plastic material transparent button (1) which can slide in the base. The button (1) has cylindrical cavities (7) in which floating pistons (2) freely circulate. The pistons have toroidal sealing joints (22) and are fitted to the base by circlips (5).
