求の範囲第４項記載の高圧水ポンプ。[Claims for Utility Model Registration] 1. A motor and a radial motor installed in a case, such as driving a piston of a piston pump fitted into a cylinder of a radially arranged cylinder block driven by a motor and an eccentric wheel provided at the end of the motor shaft. In a high-pressure water pump that is directly connected to a piston pump and sealed in an oil-filled case, a U-ring groove is formed on the cylinder chamber side of the piston and the U-ring is inserted into the piston on the side driven by the eccentric wheel of the piston. An O-ring groove is formed in the part of the piston that slides against the cylinder, and the O-ring is inserted into the piston, and a groove is provided between the piston ring groove and the O-ring groove to accommodate a material impregnated with lubricant. A high-pressure water pump containing impregnated material in the groove. 2. The high-pressure water pump according to claim 4, wherein the cylinder block is provided with a hole that communicates with the outside of the groove of the piston containing a material impregnated with a lubricant.
