Definition of hydraulic torque wrench

A high power hydraulic torque wrench is a part of a piston engine. Its function is to control the opening and closing of the valve.

The main body of the camshaft is a cylindrical bar with the same length as the cylinder block. The upper sleeve is provided with a plurality of cams for driving the valve. One end of the camshaft is a bearing supporting point, and the other end is connected with the driving wheel.

The shape of the cam is in the shape of an egg. The purpose of the design is to ensure the full intake and exhaust of the cylinder, specifically, to complete the opening and closing of the valve in as short a time as possible. Considering the engine durability and the operation of the ride, because the valve can not be opened or closed in the deceleration process produces excessive shock, otherwise it will cause serious wear of the valve, the increase of noise or other serious consequences.

In general, one cam corresponds to one valve in a inline engine, and a V engine or a horizontally opposed engine shares one cam per two valves. The rotor engine and valveless valve distribution engine do not require cam because of its special structure.
