Claims

[Scope of Claim for Utility Model Registration] 1. A hydraulic latch adjuster that is held in the cylinder head and transmits the rotational displacement of the cam to the intake and exhaust valves without creating any valve clearance, and which introduces oil from the outside. a cup-shaped main body having an oil inlet port; a plunger fitted into the main body so as to be slidable in the axial direction; and a plunger that is separate from the plunger and is slidable in the axial direction above the plunger. a plunger cap that is fitted into the plunger cap; and a separator that fits into the inner circumferential surfaces of the plunger cap and the plunger, and divides a reservoir chamber defined between the plunger and the plunger cap into two. A hydraulic lash adjuster comprising: and a sealing means provided between the separator and the plunger. 2. The lash adjuster according to claim 1, wherein the separator is tightly fixed to the inner peripheral surface of the plunger cap by press fitting. 3. The lash adjuster according to claim 1 or 2, wherein the sealing means is an O-ring, and an annular groove in which the O-ring is mounted is provided on the outer peripheral surface of the separator. . 4. The lash adjuster according to claim 1 or 2, wherein the sealing means is an O-ring, and an annular groove in which the O-ring is mounted is provided on the inner peripheral surface of the plunger.
