Claims

[Scope of utility model registration request]

This is a hydraulic valve lifter that adjusts the valve clearance by the operation of a hydraulic mechanism within the lifter body.The lifter body and a separate plate are joined to the part that contacts the cam, and the lifter body and this plate are A storage space for hydraulic oil to be supplied to the hydraulic operating mechanism is formed between the lifter main body and the plate by the recess formed in at least one of the joint surfaces, and the recess is opened to face the storage space, In a valve lifter provided with an oil supply hole P for supplying hydraulic oil to the hydraulic operating mechanism and a supply hole Q for supplying hydraulic oil to the storage space itself,
A reinforcing convex portion formed integrally with either the lifter main body or the plate is provided in the storage space, and the tip of the convex portion is brought into contact with an opposing mating member. By forming a partition wall, the storage space is arranged such that the length of the flow path connecting the oil supply hole P and the supply hole Q is longer than the length of the flow path when both the holes P and Q are connected linearly. A valve lifter characterized by partitioning
