Abstract: A hydraulic lash adjuster (1) for a valve train (16) of an internal combustion engine, said hydraulic lash adjuster (1) comprising a hollow cylindrical housing (2) and a pressure piston (3) that are axially inter-inserted for axial displacement relative to each other, a bottom (4) of the pressure piston (3) comprising a central passage (5) for hydraulic medium from a reservoir (6) enclosed by the pressure piston (3) into a high pressure chamber (8) situated between the bottom (4) of the pressure piston (3) and an opposing bottom (7) of the housing (2), said passage (5) comprising, on an end (9) oriented toward the high pressure chamber (8), a one-way valve (10) that opens toward the high pressure chamber (8), wherein a flexible disk-shaped body (11), that is capable of floating on the hydraulic medium, extends within the reservoir (6). In this way, a “break-through” of air from the reservoir (6) into the high pressure chamber (8) is avoided. During a re-suction process in the lash adjuster (1), the body (11), so to speak, follows an air funnel that is being formed in the reservoir (6) in the direction of the one-way valve (10).

Abstract: A hydraulic valve lifter including venting means to assure venting of air through the lifter and filling thereof with oil during pre-start filling of the engine oil galleries after engine assembly. Patterning of a hemispherical pushrod seat surface, and/or patterning of either or both of the mating surfaces of a pushrod seat and a piston, permits air purged from the engine through a pushrod to be vented through the lifter. Such means may be temporary or permanent and may include coatings of the surfaces with materials that are destroyed by engine action after starting. Permanent means may include surface grooves in the mating surfaces and/or small-diameter passages between the hemispherical seat surface and the cylindrical outer surface of the pushrod seat. Venting means in accordance with the invention is useful for both valve-deactivating and non-valve-deactivating valve lifters.

Abstract: Systems for valve actuation in internal combustion engines provide configurations for hydraulic lash adjusters and valve actuation valvetrain components that are particularly suitable for prevention of HLA jacking in lost motion cam environments and in valve bridge environments. In one implementation, a rocker arm may transmit motion from a lost motion cam having main event and auxiliary event lobes. Main event motion is transmitted to two engine valves through the rocker arm, a lash adjuster, lash adjuster loading component and valve bridge, which define part of a first load path. Braking motion is transmitted to one of the engine valves through an inboard valve actuator and bridge pin, which define part of a second load path. The HLA is thus disposed in a separate load path from the braking valve load and the lash adjuster loading component keeps the lash adjuster under a constant compressive force to prevent jacking.

Abstract: Provided is a variable valve device for an internal combustion engine, capable of improving engine characteristics by increasing the maximum valve lift of an intake valve to a large valve lift while preventing excessive lost motion operation of lost motion mechanisms. The variable valve device includes intake- and exhaust-side swing arms that pivot to open and close intake valves (3a, 3b) and exhaust valves (61a, 61b) in two cylinders #1, #2, intake- and exhaust-side hydraulic lash adjusters (10a, 10b, 65a, 65b) that serve as pivot points of the respective swing arms, a variable valve system that continuously varies valve lift characteristics of the intake valves and lost motion mechanisms (11) that stop opening and closing of the intake exhaust valves by lost motion of the intake- and exhaust-side hydraulic lash adjusters on the cylinder #1. The maximum valve lifts of the intake valves are set larger than valve lifts of the exhaust valves. The minimum valve lifts of the intake valves are set smaller than the valve lifts of the exhaust valves.

Abstract: A lash adjuster includes a plunger having a bottom wall with a valve hole and a peripheral wall having an oil passage hole and an inner periphery formed with a recessed groove, the plunger defining a high-pressure chamber between the bottom wall and a body, and a partitioning member having an oil passage end located above the oil passage hole. The partitioning member has an oil-passage defining portion located opposite the recessed groove and defining an oil passage between itself and a groove face of the recessed groove. The partitioning member defines a low-pressure chamber reserving a hydraulic fluid flowing through the oil passage hole, the oil passage and the oil passage end. The low-pressure chamber causes the reserved hydraulic fluid to flow through the valve hole into the high-pressure chamber. The partitioning member is formed into a cylindrical shape and extends in an up-down direction without any stepped part.
