Abstract: An improved cam follower for a vehicle engine includes a body, a spring seat, a tower, a spring and an anti-rotation member. The body defines a body diameter, a first open end, and a second end. The spring seat includes a spring seat opening and an interlock portion. The spring seat may be affixed to the first open end of the body. The spring seat further includes a spring seat diameter wherein the spring seat diameter is greater than the body diameter. The tower may be disposed in a pin housing through the spring seat opening at the first open end of the body. The tower further includes an upper flange and a spring which abuts the upper flange at a first spring end. The second spring end abuts the spring seat. The anti-rotation member accordingly may be coupled to the body via the spring seat.

Abstract: A valve operating system includes: a decompression cam member that is provided on a camshaft, and moves between an operative position C where an exhaust tappet is operated in a valve opening direction in a compression stroke and an inoperative position D where the exhaust tappet is released; an exhaust gas recirculation cam member that is provided on the camshaft, and moves between an inoperative position F where the exhaust tappet is released and an operative position G where the exhaust tappet is operated in a valve opening direction in an intake stroke of the engine; and a common centrifugal mechanism that is driven by the camshaft to operate the decompression cam member to the operative position C in a starting rotation region of the engine and to the inoperative position D after the starting, and operate the exhaust gas recirculation cam member to the inoperative position F in a low speed operation region of the engine and to the operative position G in a high-speed operation region. Thus, the valve operating system can exert both a decompression function and an exhaust gas recirculation function.

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 through which oil respectively enters and exits the lifter assembly. An elongate, hollow lifter body closed at one end is reciprocatingly disposed within the sleeve, and has a plunger reciprocatingly disposed therein. The plunger has an internal cavity at least partially defining a low pressure oil reservoir which is in at least periodic fluid communication with the oil feed hole. 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. A cap is reciprocatingly disposed within the sleeve and engaged with the plunger. Seals are provided which preclude oil from exiting the lifter assembly through the ends of the sleeve.

Abstract: In order to eliminate components in an internal combustion engine, and to thereby reduce the cost and weight while enhancing compactness in a rigid yet quiet arrangement, a valve train assembly is disclosed. The internal combustion engine has a valve with an integral valve stem, a valve lifter in engagement with a cam, and a rocker arm in engagement with the valve stem. The valve train assembly is such that the rocker arm is in engagement with the valve lifter at a first point along its length and is in engagement with the valve stem at a second point along its length. The rocker arm has a recess at the first point along its length for receiving and engaging the valve lifter therein. The valve train assembly is also such that the rocker arm has a surface at the second point along its length to thereby move the valve in response to movement of the valve lifter. The internal combustion engine also includes a mounting for the rocker arm at a point intermediate the first and second points along its length for pivotal movement thereof. With these features, the valve train assembly is such that movement of the valve lifter is imparted through the rocker arm to the valve stem in a most highly efficient and compact manner in a quiet internal combustion engine.
