    Abstract: A lifter assembly (40a) for an internal combustion engine (10), including an elongate sleeve (46) having an upper radial wall portion (48) provided with oil feed (60) and oil bleed (62) holes therethrough, through which oil respectively enters and exits the lifter assembly. An elongate, hollow lifter body (68) is reciprocatingly disposed within the sleeve, the lifter body being closed at one end (70) thereof. A plunger (72) is reciprocatingly disposed within the lifter body and has an internal cavity (74), a low pressure oil reservoir (76) 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 (78) 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 (100) is reciprocatingly disposed within the sleeve and engaged with the plunger. First (110) and second (112) 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 (52) of the sleeve, and the oil bleed hole and the other end (54) of the sleeve, whereby oil is precluded from exiting the lifter assembly through the ends of the sleeve.

    Abstract: A lash adjuster in which, when a plunger descends, a valve element moves to a valve-closed position without delay. A check valve (27) has a valve hole (28) penetrating through a bottom wall (17) of a plunger (12), a retainer (30) placed in a high pressure chamber (25) and vertically moving together with the plunger (12), and a valve element (29) capable of vertically moving in the high pressure chamber (25), between a valve-opened position at which the valve element (29) is separated from the valve hole (28) to be placed on the retainer (30) and a valve-closed position which is located above the valve-opened position and at which the valve element (29) closes the valve hole (28). When the plunger (12) is at a standstill, the valve element (29) is held at the valve-opened position by the self-weight.

    Abstract: A hydraulic lash adjusting tappet for an internal combustion engine of the type supplying oil to a passage communicating with the tappet-receiving guide bore in the engine. The tappet has a roller follower on the cam end and a registration means adjacent the opposite end for orienting the roller with respect to the engine cam. The tappet body has at least one localized collector recess disposed longitudinally coincident and peripherally spaced with the registration means. In one embodiment the registration comprises a pair of oppositely disposed flats and the tappet has a pair of diametrically opposed collector recesses interconnected by a peripheral groove spaced longitudinally therefrom to by-pass the flats and provide sufficient surface for leakage control. An oil inlet hole is formed in one of the collector recesses for supplying the lash adjuster valve in the tappet. The localized recess is aligned with the engine supply passage by the orientation of lthe registration surface. I

    Abstract: An hydraulic lash adjuster (10) for internal combustion valve gear having a body (12) defining a bore (14) with a plunger (16) slidably received in the bore (14) forming a relatively small volume high pressure hydraulic chamber (27). A valving orifice (38) is provided in the plunger for supplying hydraulic fluid to the chamber (27) upon relaxation of valve event forces and a one-way check ball valve (92) closes the orifice and the hydraulic chamber upon application of valve event forces to the plunger. The check ball has a diameter not greater than 34-1/2% of the plunger diameter, thereby enabling a smaller valve member and smaller chamber for a given body envelope. The smaller hydraulic chamber volume, when filled results in decreased volume of entrained air within the hydraulic fluid retained therein and therefore less shortening of the lash adjuster under valve event forces applied by the engine valve gear. The compactness permits addition of a roller follower without requiring increase in overall tappet size.

    Abstract translation: 一种用于内燃阀齿轮的液压间隙调节器（10），其具有限定具有可滑动地容纳在所述孔（14）中的柱塞（16）的孔（14）的主体（12），形成相对小体积的高压液压室（27） 。 在柱塞中设置有阀孔（38），用于在松动阀事件力时将液压流体供应到腔室（27），并且单向止回阀（92）在施加阀门事件时关闭孔口和液压室 力向柱塞。 止回球的直径不大于柱塞直径的34-1 / 2％，从而能够为给定的主体外壳提供较小的阀构件和较小的腔。 当填充时，较小的液压室体积导致保持在其内的液压流体内的夹带空气的体积减少，因此在由发动机气门装置施加的阀事件力下间隙调节器的缩短较少。 紧凑性允许添加滚子从动件而不需要增加整体挺杆尺寸。
