摘要： An cylinder valve controlling apparatus comprises a first rocker arm and a second rocker arm cooperating with a middle lift cam and a low lift cam, respectively, to active two cylinder valves arranged for each of the engine cylinders, respectively. The apparatus further comprises a free rocker arm cooperating with a high lift cam. During engine operation at low speeds, the first rocker arm activates one of the cylinder valves in accordance with the profile of the middle lift cam, while the second rocker arm activates the other cylinder valve in accordance with the profile of the low lift cam. During engine operation at middle speeds, a coupling including a first lever establish drive connection between the first and second rocker arms and thus the first and second rocker arms follow the profile of the middle cam. During engine operation at high speeds, with the first-mentioned coupling maintaining the drive connection, another coupling establishes drive connection between the free cam follower and the first rocker arm. Thus, the first and second rocker arms activate the corresponding cylinder valves in accordance with the profile of the high lift cam.

摘要： An intake- and/or exhaust-valve timing control system for internal combustion engines in which a ring gear mechanism is provided between a timing pulley and a cam shaft for adjusting the phase angle between the pulley and the cam shaft. A drive mechanism is also provided for driving the ring gear mechanism depending upon the operating state of the engine. The drive mechanism includes a hydraulic circuit having oil supply and exhaust passages, a flow control valve having a spool valve for controlling the amount of working fluid flowing through the hydraulic circuit, a controller for monitoring the operating state of the engine, and an electromagnetic actuator having a plunger rod for actuating the flow control valve in response to the control signal from the controller. The flow control valve and the actuator are integrally mounted in the cylinder head. Therefore, relative friction between the facing ends of the spool valve and the plunger rod is avoided.

摘要： A parallel guide portion as an integral structure of a sprocket and a vane, as well as a slant guide portion, are arranged alternately on the same circumference, with circumferential gaps being formed between said guide portion and the parallel guide portion, said guide portion having a shape such that the circumferential gaps become smaller in one axial direction of a cam shaft. Wedge members are disposed in the circumferential gaps respectively and are moved in one axial direction to fill up the circumferential gaps, thereby fixing the phase between the sprocket and the vane into a locked state. The wedge angle of each wedge member is set sufficiently small and, by utilizing varying torques acting on the cam shaft, said members are each moved and locked in one axial direction with a spring. Said members are actuated in an opposite axial direction with oil pressure to release the locked state, thereby permitting a phase angle control. By utilizing a varying torque acting on the cam shaft, the phase of the cam shaft is returned for itself to an intermediate position and is locked without looseness.

摘要： A variable valve timing control system of an internal combustion engine includes a hydraulically-operated phase converter disposed between a sprocket and a camshaft, and having a phase-advance hydraulic chamber and a phase-retard hydraulic chamber for changing an angular phase of the camshaft relative to the sprocket. An electric pump is provided to supply working fluid selectively to one of the hydraulic chambers via a directional control valve. Also provided is a check valve disposed in a discharge line of the pump for permitting flow in a direction that the working fluid flows from the pump to the directional control valve and preventing any flow in the opposite direction, so as to prevent a pulse pressure arising from alternating torque exerted on the camshaft from being transmitted from either one of the hydraulic chambers via the discharge line to a discharge port of the pump.

摘要： A valve timing adjusting mechanism houses a timing adjusting gear assembly within a liquid-tight housing which prevents working fluid used to adjust the timing from coating a timing gear engaging a timing belt. The working fluid is introduced within the housing to exert timing adjusting force on the timing adjusting mechanism, resulting in relative angular displacement between a camshaft and the timing gear which is manifested as an adjustment to the valve timing. With this arrangment, the timing belt is free of working fluid. Therefore, the lifetime of the belt retains its design value and slip between the timing belt and the timing gear can be prevented.

摘要： A hydraulic control system for an internal combustion engine, includes a driven mechanism driven by hydraulic pressure fed through a flowing passage change-over valve. The flowing passage change-over valve includes a valve body formed with a plurality of ports which are respectively communicated with the supply passage and the oil passage, and a spool valve body slidably disposed in the valve body to open and close the plurality of ports, the ports including a supplying port communicated with the supplying passage.
