    Abstract: The invention proposes a switching element (1) for a valve train of an internal combustion engine, said switching element comprising an outer element (2) and an inner element (4) that is arranged for axial displacement in a bore (3) of the outer element (2), each of the outer element (2) and the inner element (4) comprising at least one reception (12, 9) aligned to each other in an axially distant relative position which is achieved through a lost motion spring (8), at least one piston (10) being arranged in at least one of the receptions (12, 9) for sliding toward the other of the receptions (12, 9) to couple the inner element (4) to the outer element (2) in said relative position, and a high-position stop for defining said relative position being arranged between the inner element (4) and the outer element (2). The inventive high-position stop is made as a separate element (16) such as a disk or a circlip with a variable thickness that is fixed on one of the outer element (2) and the inner element (4) and cooperates with a stop surface of the other of the outer element (2) and the inner element (4). These extremely simple fabrication measures enable an alignment of the receptions (9, 12) for achieving coupling.

    Abstract: A hydraulic system (1) for a switchable valve drive element (10) of an internal combustion engine (33) is provided and includes a throttled connection (13) created from a second channel (9), used to actuate a hydraulic play-compensation element (11) using hydraulic fluid, directly to an external radial side (12) of a coupling element (8). The coupling element (8) is supplied by a first channel (7) with the switching hydraulic pressure. These measures make it possible to keep the first channel (7) as free as possible of undesired air.

    Abstract: A lifter assembly for an internal combustion engine, including an elongate sleeve having an upper radial wall portion provided with oil feed and oil bleed holes therethrough, through which oil respectively enters and exits the lifter assembly. An elongate, hollow lifter body is reciprocatingly disposed within the sleeve, the lifter body being closed at one end thereof. A plunger is reciprocatingly disposed within the lifter body and has an internal cavity, a low pressure oil reservoir at least partially defined by the plunger internal cavity, the low pressure oil reservoir in at least periodic fluid communication with the oil feed hole, whereby oil from the oil feed hole is received into the low pressure oil reservoir. A high pressure oil reservoir is at least partially defined by the plunger and the lifter body closed end, and is in one-way fluid communication with the low pressure oil reservoir, whereby oil is received into the high pressure reservoir from the low pressure oil reservoir. A cap is reciprocatingly disposed within the sleeve and engaged with the plunger. First and second seals are located between an outer circumferential surface of the lifter body and an outer circumferential surface of the cap, respectively, and an inner circumferential surface of the sleeve, the seals respectively located between the oil feed hole and one end of the sleeve, and the oil bleed hole and the other end of the sleeve, whereby oil is precluded from exiting the lifter assembly through the ends of the sleeve.

    Abstract: A mechanical oil filtration and oil flow re-direction system for a hydraulically actuated valve lifter. Pressurized oil is directed to the lifter through a series of controlled clearance passages prior to gaining access to the internal cavity of the lifter. Once inside the lifter, the oil is deflected off of an insert that directs the oil towards the upper end of the lifter and the push rod seat. The oil flow is then directed downwards into an oil deflector supply hole and into the internal cavity of the lifter and the chamber containing the lifter check ball and seat. In use, the system restricts particulates from the lifter, and re-directs particulates that do access the lifter to pre-determined locations within the lifter to minimize operational impairment of the lifter from particulate contamination.

    Abstract: A valve actuation sub-assembly for an internal combustion engine, the sub-assembly being adapted for attachment to an engine block (11B) and including a conventional roller follower (21) and a deactivating roller follower (47). The sub-assembly comprises a follower guide member (71) defining a first guide receptacle (81) for receiving an upper portion (87) of the conventional roller follower (21), and a second guide receptacle (83) for receiving an upper portion (93) of the deactivating roller follower (47). In accordance with the invention, neither upper portion (87,93) will be received within the guide receptacle (81,83) intended for the other upper portion, thus preventing assembly errors, wherein one roller follower type is installed in a location on the engine intended for the other roller follower type.

    Abstract: A hydraulic lash adjuster of the type including a ball plunger (61) defining a passage (63), or a body portion (85) defining a passage (87). A metering valve is disposed in the passage, and in accordance with the invention (FIGS. 2-4), a shank portion (77) of the metering pin (73) defines a metering passage (81). During normal operation, pressure in the low pressure chamber (21) biases the metering pin (73) upward, to a position in which fluid can flow from the chamber (21), through the metering passage (81), to the external surface (71) of the ball plunger (61). When pressure in the chamber (21) is very low, or negative, a head portion (75) is disposed against a seat (69) in the manner of a check valve. The up and down movement of the pin (73) prevents the metering passage (81) from becoming plugged with contaminants.

    Abstract: The invention concerns a hydraulic play-compensation element including a groove (11) in the housing (1) to be located in such a way that, whatever the position of the plunger (2), a length (19) of the plunger is always supported by the cylinder wall above the groove and the securing ring (12) is centered radially around the plunger by means of a recess (14) in the plunger, the recess having a ramp at least at its lower end. The invention thus avoids weakening of the material in the upper part of the plunger.
