摘要： A sealed type lash adjuster (100A) includes a plunger (2A), a body (1) in which the plunger (2A) is inserted in a fitting manner, a first sealing means (5) provided between the plunger (2A) and the body (1), and a second sealing member (20A) that can prevent or suppress intrusion of an engine oil from an outside. The second sealing means (20A) seals a portion of the plunger (2A) exposed from the body and is arranged so as to cover a clearance (K) formed between an open end portion of the body and the plunger (2A). More specifically, the second sealing member (20A) has a one-end portion (20aA) and an other-end portion (20bA) as sealing parts having a function of preventing or suppressing intrusion of the engine oil from the outside.

摘要： The liquid is sealed in the lash adjuster so that the volume “V1” of the gas, in the reservoir chamber when the lash adjuster is being produced and the plunger protrudes from the body, is equal to or more than 1.24 times as great as the sum of the volume “Vo1” of the liquid discharged from the high-pressure chamber when the plunger moves downward, and the increase “Vo2” in the volume of the liquid that expands, due to heat, when the temperature of the gas in the reservoir chamber is increased from the production temperature to the maximum use temperature, and the ratio of “V1” to “Vo1+Vo2” is equal to or higher than a ratio, which is derived based on the production temperature and the maximum use temperature, when the inner pressure of the lash adjuster increases by 500 kPa at maximum.

摘要： A support element for the valve train of an internal combustion engine, having a hollow cylindrical housing that holds a displaceable piston. The piston has a hollow cylindrical pressure part and a pot-shaped work part axially adjacent thereto. An inner space of these parts forms a storage space for hydraulic medium. A high pressure space is defined by a base of the work part and the housing. The storage space and the high pressure space are connected hydraulically by a non-return valve with a ball for automatic lash compensation of the valve train. The piston is supported by a compression spring on the housing base, and a retaining ring is arranged radially between the pressure part and the housing, which limits axial travel of the piston. The ball is movably held in the base of the work part in an axial ball guide having first and second integrally formed ball seats.

摘要： A piston-cylinder cup-type tappet for an internal combustion engine comprises an outer housing defining a first cavity and a hollow piston having a second cavity with the hollow piston being disposed in the first cavity. An aperture provides for fluid flow between the first and second cavities. An inner housing is disposed in the first cavity with the inner housing defining a third cavity. The piston is received in the third cavity of the inner housing wherein the piston and the inner housing jointly define a throttle gap. A compression spring is disposed in the third cavity and supports the hollow piston and the inner housing. A check valve is disposed between the second and third cavities and permits fluid flow from the second cavity to the third cavity. A chamber is defined by the first cavity, the second cavity, the third cavity, the aperture and the throttle gap. An incompressible fluid fills this chamber. The chamber is closed off from the exterior thereof by a fluid impermeable wall and at least a portion of this wall adjacent the first cavity is designed as an elastically resilient spring bellows.
