Mechanism for straightening bodywork of damaged vehicle comprises piston in master cylinder displaced by cam which transmits oil into receptor cylinder to displace piston and strike cylinder bottom

摘要

The bodywork straightening mechanism comprises a master cylinder (CE) in which a piston (PE) is displaced under the action of a cam (C). The piston transmits oil by means of a flexible tubing (F) into a portable receptor cylinder (CR) connected to the vehicle. The oil displaces a receptor piston (PR) which, at the end of its travel, strikes the bottom of the receptor cylinder (FA) 50 to 100 times per second. This striking creates a straightening force in direct relation to the weight of the receptor piston and the square of its speed at the moment of impact.
