[0027] This application improves the adaptability and diversification of functions of the high-pressure integrated manual pump. It can be used for single-acting hydraulic cylinders and double-acting hydraulic cylinders, can use pipe connection or plate connection, has a reversing function to realize the switching of the oil circuit, and has a pressure self-adaptive function through the action of the pressure relief valve. It increases the displacement in a low-pressure system to improve work efficiency, and adapts the displacement in a high-pressure system to reduce the labor intensity during operation;

[0028] Specifically:

[0029] In this application, hydraulic oil enters the valve body assembly through the filter assembly. The hydraulic oil passes through the check valve and, as needed, through the reversing valve. The oil outlets of the reversing valve are respectively connected to the hydraulic actuator and the safety valve to maintain the pressure in the hydraulic system, so that this application can be applied to double-acting cylinders. By switching the oil circuit of the reversing valve, the lifting or lowering of the cylinder can be realized;

[0030] When applied to a single-acting cylinder, the oil port position can be changed to provide pressure to the cylinder in the forward direction and suck oil from the oil cavity in the cylinder in the reverse direction, improving the efficiency and smoothness of the self-weight descent.
