Claims

[Claims for Utility Model Registration] 1. A hollow cylindrical body with a bottom and an oil hole at the bottom, which is slidably fitted into the body to form a high pressure chamber between the inner surface of the bottom. a bottomed hollow plunger; an elastic body provided within the high pressure chamber to bias the plunger away from the opening end of the body; and an elastic body also provided within the high pressure chamber for controlling opening and closing of the oil passage hole. a check valve and a check valve cage holding the check valve;
a push rod socket which is slidably fitted into the body and has a bottomed cylindrical shape with a downward opening and is located such that the lower end of the opening is connected to the open end of the plunger; It consists of an oil reservoir defined by the push rod receiving side surface of the rod socket and the inner circumferential surface of the body, and an oil reservoir defined by the plunger and the push rod socket. A hydraulic lifter characterized in that one or more oil introduction holes are provided on the lower side surface of a cylinder forming an oil reservoir chamber, and one or more oil inlet/output holes are provided on the upper side surface of the cylinder. 2. Utility model registration claim 1, characterized in that a circumferential groove communicating with the oil inlet/outlet hole is provided on the outer circumferential surface of a cylinder consisting of a plunger and a push rod socket defining the oil reservoir chamber. Hydraulic lifter as described in Section. 3. A circumferential groove is provided on the outer circumferential surface of the cylinder made up of the plunger and the push rod socket on the oil receiving side from the position of the oil inlet/outlet hole, and an oil groove is provided to connect the oil inlet/outlet hole and the circumferential groove. The hydraulic lifter according to claim 1, which is characterized by being provided with a groove. 4. Utility model registration claim 1, characterized in that an oil groove is provided that connects a circumferential groove that communicates with the oil inlet/outlet hole and a circumferential groove provided on the oil receiving side than the oil inlet/outlet hole. Hydraulic lifter described in. 5. The hydraulic lifter according to claims 1 to 4 of the utility model registration claim, wherein the oil inlet/outlet hole is a slit at the end of the push rod socket adjacent to the plunger. . 6. The hydraulic lifter according to claims 1 to 4 of the utility model registration claim, wherein the oil inlet/outlet hole is a slit at the end of the plunger adjacent to the push rod socket. .
