摘要： PROBLEM TO BE SOLVED: To provide a lash adjuster capable of shortening the total length as compared with former ones and a method for assembling a lash adjuster capable of avoiding scarring on the inner circumference surface of a body. SOLUTION: Since a bottom body 21 is attached to an opening after inserting a plunger 3 from the opening provided at a bottom side of a body 2, damages on the inner circumference surface of the body 2 is avoided. Since the extending-up quantity of the plunger is regulated by a recess 25 provided on the body 2 and a projection 27 of the plunger 3, the total length of the lash adjuster is shortened as compared with the former ones.

摘要： OBJECT To provide a hydraulic lash adjuster capable of retaining a large amount of hydraulic oil in a reservoir communicated with a high-pressure chamber when the engine is stopped. MEANS FOR SOLVEING THE PRPBLEM A hydraulic lash adjuster including: a cylindrical body (24) having an upper open end, a closed bottom, and a second oil supply hole (27a) formed in the sidewall of the cylindrical body; and a plunger having a top end serving as a plunging end, a sidewall, a bottom end, a high pressure chamber (29) at the lower bottom, and a first oil supply hole (24b) formed in the sidewall, the plunger being slidable on the inner wall of the body. The plunger has a reservoir (28) that communicates with an external oil supply line (32) via the first oil supply hole (24b) and the second oil supply hole (27a). The lash adjuster is provided with a check valve (40a) for opening the oil supply hole (24b) by the oil pressure led from an external oil passage (32) to the oil supply hole (24b). The check valve (40a) is arranged in an annular communication passage (T) formed between the sidewalls of the plunger (26) and the body (24) for communicating the oil supply hole (27a) with the oil supply hole (24b). Leak-down oil is recycled while the engine is in operation. When the engine is stopped, the check valve (40A) closes the oil supply hole (24b). Accordingly, a large amount of hydraulic oil is stored in the reservoir (28) communicated with the high pressure chamber (29), with the oil level H in the reservoir (28) never being lower than the open end of the body (24).

摘要： PROBLEM TO BE SOLVED: To make a plunger easily retreat from/enter into a body when the plunger is unnecessarily delivered (when a pump-up phenomenon occurs), without making the plunger easily retreat from/enter into the body, when pressing a valve of a valve system (when abutting on a cam nose).SOLUTION: A sub-leak passage 50 for leaking oil to a low pressure oil chamber 25 from a high pressure oil chamber 15, is arranged separately from a leak clearance 40 between an outer peripheral surface of the body 10 and an inner peripheral surface of the plunger 20, and a sub-leak valve 55 is arranged to the sub-leak passage 50. The sub-leak valve 50 is constituted so as to open the sub-leak passage 50 when an oil pressure difference between the high pressure oil chamber 15 and the low pressure oil chamber 25 is a small oil pressure difference state smaller than a predetermined oil pressure difference, and to close the sub-leak passage 50 in a large oil pressure difference state larger than the predetermined oil pressure difference, when the plunger 20 retreats and enters.
