TECHNICAL FIELD

[0001] The utility model relates to the field of hydraulic element, concretely is a hydraulic element with anti -blocking interface. BACKGROUND

[0002] A complete hydraulic system is composed of five parts, namely power element, execution element, control element, auxiliary element and hydraulic medium. The function of power element is to convert the mechanical energy of prime mover into the pressure energy of liquid, which refers to the oil pump in the hydraulic system, which provides power to the whole hydraulic system.

[0003] The Chinese patent with publication number CN209444654U discloses a hydraulic element, which comprises a cylinder body and a flow distribution disc. On the sealing end surface of the cylinder body and / or the flow distribution disc, annular static pressure oil grooves and damping oil grooves that communicate with the static pressure oil grooves and extend in the direction of the flow distribution window are formed along the inner side and / or the outer side of the flow distribution window. The utility model can guide the high-pressure oil of the flow distribution window into the inner and outer sealing bands between the contact surfaces of the cylinder body and the flow distribution disc through the damping oil grooves. When the whole machine works under high pressure and high speed, the oil in the sealing surface between the cylinder body and the flow distribution disc and the static pressure oil groove will be compressed. At this time, the high-pressure oil stored in the static pressure oil groove will generate an oil pressure reaction force after being subjected to a certain pressure. This reaction force can partially or completely offset the axial force received by the cylinder body, thereby reducing the wear caused by the tilting of the cylinder body.

[0004] The hydraulic element of the above-mentioned patent may be blocked by impurities in the hydraulic oil when the hydraulic oil is input into the hydraulic element through the pipeline, which may cause the hydraulic element to malfunction. UTILITY MODEL CONTENTS
