Abstract: 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.

Abstract: 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.

Abstract: The invention relates to an improved system of electro-mechanical hydraulic valve lifters for piston engine automobiles that increases fuel economy and reduces fuel emissions. The electro-mechanical hydraulic valve lifters contain that enclose a magnetorheological fluid chamber, containing magnetorheological fluid. A control module manages voltage sent to the magnetorheological fluid in the magnetorheological fluid chamber. The control module introduces various amounts of magnetic flux to the magnetorheological fluid in the magnetorheological fluid chamber. The magnetorheological fluid's viscosity changes based on the amount of magnetic flux applied to it from the electromagnets and, along with the magnetorheological fluid chamber spring, controls how much an intake and exhaust port of the spark plug engine opens to control the amount of fuel used and exhaust let out of the engine.

Abstract: An electromagnetically driven valve includes a driven valve having a stem extending in a prescribed direction and an umbrella-shaped portion provided at a tip end of the stem and opening/closing an intake/exhaust port, a lower disc and an upper disc having one ends coupled to the stem and the other ends supported by a disc support base so as to allow free oscillation of the disc respectively and oscillating around the other ends so as to cause the driven valve to carry out reciprocating motion in the prescribed direction, a lash adjuster provided in the stem, and a guide ring guiding the lash adjuster along the prescribed direction. The lash adjuster contracts and expands in the prescribed direction and accommodates displacement of the stem produced in a direction orthogonal to the prescribed direction as a result of reciprocating motion of the driven valve. With such a structure, the driven valve carries out smooth reciprocating motion.

Abstract: A hydraulic lash adjuster of the type in which the plunger assembly (15) includes a ball plunger element (50), and defines a valve opening (57) in the lower plunger member (19). A check valve member (53) is seated in the valve opening (57), for opening the valve opening in response to a relative decrease in the pressure in a high pressure chamber (23). The ball plunger element (50) includes a metering valve element (45) movable between an outward position (FIG. 1) and an inward position (FIG. 2). An elongated member (65) is fixed to move with the metering element (45), and includes a lower end (67) juxtaposed the valve opening (57). When the metering element (45) is in its inward position, the lower end (67) engages the check ball (53) and lifts it from the valve opening, thus facilitating assembly of the lash adjuster, filled with fluid, into an engine.
