Abstract
A load alternation counting device for an actuation device that is periodically hydraulically loaded has a cylinder and a piston sealingly positioned within the cylinder and axially displaceable therein. A pressure connector is provided for connecting the cylinder to a hydraulic loading device of the actuation device such that the piston is axially loaded when hydraulic loading of the actuation device occurs. A counter is switchable by an axial displacement of the piston within the cylinder. A spring for biasing the piston in a direction away from the counter is provided. The spring has a spring force such that switching of the counter by the axial displacement of the piston occurs only when a preset hydraulic pressure is surpassed.
Claims6
A load alternation counting device for an actuation device that is periodically hydraulically loaded, said load alternation counting device comprising:
- a cylinder;
- a piston sealingly positioned within said cylinder and axially displaceable therein;
- a pressure connector for connecting said cylinder to a means for hydraulically loading the actuation device such that said piston is axially loaded when hydraulic loading of the actuation device occurs;
- a counter switchable by an axial displacement of said piston within said cylinder;
- and
- a spring for biasing said piston in a direction away from said counter, wherein said spring has a spring force such that switching of said counter by the axial displacement of said piston occurs only when a preset hydraulic pressure is surpassed.
