Abstract

In modern mechanical engineering, in construction and road, farm, meliorative, timber, industrial, and other land vehicles of special and general purpose hydraulic actuators of working elements, which have advantages regarding speed and smoothness of reverse or separate management, change of position of the car, accuracy of positioning, and dispensing of power impact on working bodies are widely applied. At the same time, the working pressure is optimized for the prevention of destruction of the hydraulic line of high pressure and unauthorized emission of working liquid in a hydraulic system; however, under operating conditions, the probability of emission of working liquid in the atmosphere remains. For the increase in environmental safety, protection systems of a hydraulic actuator are applied. Among the known ways of protection, a technical solution in which the locking device is equipped with the relieving valve is considered. However, the analysis of its work shows that at operation of a protection system of a hydraulic actuator, the locking device has an essential shortcoming. For the purpose of elimination of this shortcoming, it is offered to optimize not only operating pressure in a hydraulic system but also a design of the locking device.
