Abstract: A driver that reciprocates has its reciprocation divided into a non-actuating portion and an actuating portion. The driver in one embodiment positions a carrier that has two pins, each pin being slidably mounted in its slot on a housing. One of the pins is an output pin that may be linked to operatively position a valve of an internal combustion engine. The two slots are configured such that each pin, during its motion range, does effect a capture of the other pin such that the captured pin is generally stationary. When the output pin is captured, the driver reciprocation causes the non-output pin to perform a lost-motion traverse of its slot. When the non-output pin is captured, the driver reciprocation actuates the output pin. A linked pair of such embodiments driven by a single driver can thus alternately actuate two valves.

Abstract translation: 往复运动的驾驶员的往复运动被分成非致动部分和致动部分。 在一个实施例中的驱动器定位具有两个销的托架，每个销可滑动地安装在其壳体中的槽中。 其中一个销是可以连接以可操作地定位内燃机的阀的输出销。 这两个槽被构造成使得每个销在其运动范围内确实影响另一个销的捕获，使得捕获的销通常是静止的。 当捕获输出引脚时，驱动器的往复运动导致非输出引脚执行其插槽的空运行。 当非输出引脚被捕获时，驱动器的往复运动会激活输出引脚。 由单个驱动器驱动的这种实施例的链接对由此可以交替地致动两个阀。

Abstract: An internal combustion engine includes a driving shaft, a pair of camshafts for driving engine valves, a transmission connecting the driving shaft to a first of said camshafts and a transmission connecting the first camshaft to the second camshaft. The transmission connecting the two camshafts to each other includes a pair of articulated parallelogram mechanisms each having two crank members rotatable with end portions of the camshafts and connected to each by means of a connecting rod. The crank members are made up of circular discs eccentrically mounted on the camshafts and rotatably received in circular openings formed at the ends of the respective connecting rod. The two crank members rotatable with the same camshaft are spaced from each other by a determined angle.

Abstract: A continuously variable valve lift device for a vehicle is provided, which includes a drive shaft rotating in association with a crank shaft and having a drive cam formed on an outer periphery thereof, a locker arm shaft provided apart from the drive shaft and having one end that supports a rocker arm rotating and rocking in association with the drive cam, output cams rotatably installed on the drive shaft to interlock with the other end of the rocker arm, and a variable drive part straightly moving the rocker arm shaft in a vertical direction of the rocker arm shaft to vary a valve lift. When a valve is shifted from the high-lift state to the low-lift state, a pumping loss is reduced to improve the fuel consumption ratio. Also, since an advance function is provided, an exhaust-side CVVT can be deleted to greatly reduce the manufacturing cost.

Abstract: An engine with intake and exhaust valves that may be controlled with a circular cam lobe is provided. The rotating axis of the circular cam lobe is offset from the physical center of the cam lobe. This permits the cam lobe to impart a reciprocal opening and closing of the valve. To maintain the valve in the closed position, the interconnection between the cam lobe and the valve 12 may have a spring which is compressed to allow the valve to remain closed for a set duration of time while the cam lobe continues to rotate.
