Description

Technical Field

[0001] The utility model belongs to the technical field of oil replenishment valves and relates to a series oil replenishment valve body with a filtering device. Background Art

[0002] During actual use of the oil replenishing valve, hydraulic oil passes through the oil inlet and pushes the sealing ball open under the action of pressure to enter the oil replenishing valve. Under the action of the cylindrical sealing surfaces at both ends of the piston and the piston cylinder, the oil circuit is not connected to the oil tank. When the guide rod hits the piston ball surface, it drives the piston to move in the direction of movement. When the cylindrical sealing surface on the piston separates from the piston cylinder, the oil circuit is connected to the oil tank to achieve oil replenishment.
