Abstract: A tappet comprises a foot having a convex cam contact surface and an axially extending hub, a tappet body having a lower body portion with a lower axial bore formed therein to receive the axially extended hub of the foot, and a bearing assembly positioned between the foot and the lower portion of the tappet body. The cam contact surface operates in a frictional relationship with a cam lobe of a rotating cam. The frictional relationship between the cam lobe and the cam contact surface of the foot induces the foot to rotate about the center line of the tappet. The bearing assembly operates to reduce friction as the foot independently rotates axially about a center line of the tappet body.

Abstract: A damping mechanism for a lost motion hydraulic actuator utilizes a thin edge orifice in cooperation with a communication passageway between the upper and lower chambers controls the damping of the upper piston on closure. The upper piston is operatively connected to the engine valve of an internal combustion engine. A communication port from the upper chamber to the communication passageway is closed off as the upper piston returns to its normal position forcing the flow of the hydraulic fluid through the thin edge orifice. In this manner the viscosity of the hydraulic fluid does not control the damping of the actuator and the noise factor is substantially reduced.
Abstract translation: 用于空转液压致动器的阻尼机构利用与上部和下部腔室之间的连通通道配合的薄边缘孔口来控制上部活塞在关闭时的阻尼。 上活塞可操作地连接到内燃机的发动机阀。 当上活塞返回到正常位置时，从上腔室到连通通道的连通口关闭，迫使液压流体流过薄边缘孔口。 以这种方式，液压流体的粘度不能控制致动器的阻尼，并且噪声因子显着降低。

Abstract: A reservoir height extender for a lash adjuster assembly (150) comprising an inverted hollow insert member (60) disposed in fluid reservoir chamber (42) within a plunger member (40) of assembly (150). Plunger member (40) is reciprocally moveable within a bore (38) of a body member (36) having a first fluid passageway (48) adapted to receive fluid from a fluid source and which communicates with a second fluid passageway (46) in plunger member (40) adapted to enable the fluid to flow into fluid reservoir chamber (42). Insert member (60) is displaced from a wall of plunger member (40) surrounding chamber (42) for a distance sufficient to provide a third fluid passageway (68) therebetween which communicates between passageway (46) and an opening (64) through insert member (60) that is higher than passageway (46) and which enables a substantial increase in the level of fluid within reservoir chamber (42).

Abstract: A reaction member located above an angled rocker arm induces the latter to pivot once a telescopically extendible hydraulic tappet, under the influence of a cam, has lifted the rocker arm sufficiently to engage an apex thereof against the reaction member. The tappet includes a piston which defines therein a variable volume chamber into which hydraulic fluid may be readily introduced via a solenoid control valve, but only slowly discharged. The degree of extension of the tappet controls the valve lift induced by the rocker arm.

Abstract: A hydraulic lash adjuster for valve gear of an internal combustion engine, the hydraulic lash adjuster being of the type which operates from oil received under pressure from a gallery provided in the engine lubricant supply system to compensate for lash in the valve train. The body of the lash adjuster has a movable plunger assembly provided therein including upper and lower plunger members each having a bore therein which define upper and lower fluid reservoirs, respectively. A one way check valve is located between the lash adjuster body and the lower plunger member. A thin walled, cup shaped metal separator is received in the lower end of the upper plunger member for fluidly isolating the fluid reservoirs. The separator member is held in place by a plurality of outwardly turned retaining tabs extending from the open end thereof which engage the upper end of the lower plunger member. Annular metering passages meter the pressurized engine oil for supplying fluid to the lower and upper fluid reservoirs. A passageway in the top end of the upper plunger member conveys fluid from the upper fluid reservoir to a reaction surface located on the upper plunger member.
