摘要： A hydraulic lash adjuster having a reduced number of elements, yet capable of suppressing air from infusing into a high-pressure chamber. A plunger is fitted in a body. A reservoir is formed in the plunger. The plunger's head portion is formed with a communication hole for communicating its interior with its exterior. A high-pressure chamber is disposed and between the plunger and the body. An oil supply hole is formed in the peripheral wall of the plunger. A return spring is provided between the body and the plunger. A valve mechanism is provided at the plunger's bottom. Provided on the inner periphery of the plunger is an inclined area, subjected to impingement of oil jet ji and serving as an impingement area, such that the impingement area is inclined to fall in the direction of the ejected oil as the area nears the plunger's head portion.

摘要： In a hydraulic compensation element for the valve train of an internal combustion engine, with a circular cylindrical housing (32) that has, in its bore (35), an axially movable pressure piston (36) with a reservoir (37) for oil as a hydraulic medium, a sleeve-like deflection element for oil is arranged in the interior of the pressure piston (36). The oil can be introduced through a radial feed hole of the housing (32), a rising channel (42), and an end-side opening (46) of the deflection element into the reservoir (37) of the pressure piston (36). The deflection element is constructed as a circular cylindrical inner sleeve (40) that has, on one axial end, an oversize dimension relative to the inner diameter of the pressure piston (36), and the inner sleeve (40) is fixed in the pressure piston (36) with a positive and non-positive fit connection.

摘要： An improved SHVL for an internal combustion engine comprises an improved arrangement for locking a spring tower into a pin housing. The spring tower is provided with an annular OD groove as in the prior art. The pin housing ID groove is modified to have a two-step groove comprising two adjacent regions having different depths (different diameters) and having a distinct transition lip therebetween. A spring clip of the correct size seats properly in the spring tower groove and in the lesser-diameter pin housing groove, resulting in a correct overall length of the SHVL. Any oversize clip is caught between the lower lip of the spring tower groove and the transition lip of the two-step pin housing groove, resulting in a SHVL distinctly shorter than nominal, which is easily detected by either direct length measurement or a gauge.

摘要： A switchable valve train member, such as a deactivating valve lash adjuster or a deactivating hydraulic valve lifter, including a pin housing slidably disposed within an axial bore in a body. A transverse bore in the pin housing contains a retractable locking pin that engages a feature in the body including a locking surface whereby the body and the pin housing are locked together for mutual actuation by rotation of a cam lobe. A lash ring at the outer end of the body includes a portion extending into the axial bore that limits the travel of the pin housing within the body and thereby sets the internal mechanical lash in the switchable member. The axial thickness of the lash ring may be varied between assemblies to compensate for manufacturing variation in the components and is secured to the body in any of various configurations.

摘要： A hydraulic lash compensation device for an engine includes a plunger assembly slidingly received within a body bore to define a high pressure chamber. The plunger assembly includes a lower pressure chamber, an upper plunger element, and a lower plunger element. A mechanical lift loss feature includes a generally annular lift stop member retained to the upper plunger element by an adjustment member that extends through the lift stop member and is adjustably received in upper plunger element. The lift stop member is biased away from upper plunger element by a spring. When the upper plunger element is received into the body, the upper plunger element is offset a predetermined distance from the lower plunger element by virtue of the lift stop member's engagement with the lower plunger element. The offset is adjustable based on the position of the lift stop member relative to the upper plunger element.

摘要： The freely rotatable hydraulic pivot element for an internal combustion engine has four oil inlets which are in fluid communication with the lash adjusting element inside the pivot element and in fluid communication with the oil gallery by using four more equally spaced oil inlets in the outer housing of the cylinder head while still in fluid communication therein. The use of four or more oil inlets are in the same radial plane of the outside cylindrical housing of the pivot element.

摘要： A valve-deactivation hydraulic valve lifter including a recessed face on the pin housing for making contact with the a crowned surface region of a roller follower. The lifter includes a pin housing that is slidably disposed within an axial bore in a lifter body. Pins for variably locking the pin housing to the lifter body may be disengaged to place the lifter in lost-motion mode by application of engine oil to the outer ends of the pins. A surface of the pin housing, preferably configured as a dished surface, is formed on the bottom end face of the pin housing that approaches the cam-following lifter roller for making contact with the roller follower so as to avoid contacting the roller follower's crowned surface region.
