ツシユアジヤスタ。 It has a cylindrical outer plunger fitted into a cylinder provided on the rocker arm or cylinder head, and a cylindrical inner plunger having an orifice at the bottom is slidably fitted into the outer plunger, and the open end of the inner plunger is fitted into the outer plunger. A plunger head is placed in the outer plunger in contact with this, and a plunger head is placed at the bottom of the inner plunger only in the direction from the reservoir chamber formed inside the inner plunger to the high pressure chamber formed by the inner plunger and the outer plunger. A check valve is placed to allow oil to flow, and the reservoir chamber and oil inlet are communicated through an oil supply port formed in the plunger head, and the oil inlet is connected to an oil supply system formed in the rocker arm or cylinder head. The plunger head has a small hole that communicates with the atmosphere through an outlet formed in the rocker arm.In a hydraulic valve brush adjuster, the plunger head has a single oil port above the reservoir chamber. A plug is arranged, a space is formed as an oil passage between the outer surface of the plug and the plunger head, and this space is communicated with the atmosphere through a small hole in the plunger head, and an oil supply port in the plunger head is connected to the atmosphere. A hydraulic valve latch adjuster characterized by being connected to the engine's oil supply system.
