摘要： A decompression device for an internal combustion engine in which the control parts which open and close the exhaust valves of the combustion chambers include a rocking lever acting on the valve. The decompression device includes an eccentric bearing on which the rocking lever is freely mounted, rotation of the eccentric bearing thus moving the axis of the rocking lever to prevent full closing of the exhaust valve, that is, provide decompression of the chamber. The eccentric bearing may be turned to reference position at which it permits full closing of the exhaust valve by either manual or automatic means.

摘要： An air-cooled internal combustion engine is provided with noise reducing means without increasing space requirements. A blower is provided to direct cooling air to at least one engine wall, for example a cylinder wall, and an engine accessory such as a fuel tank, which is needed in any event, forms a conduit to convey cooling air away from the engine wall. The cooling air path is lined with noise absorbing material, such as rock wool, held in position by a foraminous sheet. Where the blower impeller is rotatably mounted on a fixed shaft, similar noise reducing means can be provided on the shaft on the downstream side, the upstream side, or both, of the impeller.

摘要： A piston engine of the type in which opposed pistons drivingly engage a shaft between the pistons by engagement with cam parts fixed on the shaft. A return spring compressible in a direction parallel to the axis of the pistons is spaced laterally from this axis. Pivotally mounted levers engage the spring ends and the pistons to urge the latter against the cam parts. Cups may cover the spring ends, the outside of these cups facing a common scavenging chamber such that inward and outward movement of the cups under the action of the springs and the levers pump air into and out of this scavenging chamber.

摘要： In an internal combustion engine, the engine casing has segmental flanges defining one or more annular guideways extending generally at right angles from the camshaft. At least one correspondingly annular segmental element is slidably disposed in each guideway such that one end thereof bears against the cam and the other end provides a seat for an associated valve push rod. Reciprocation of the element along the annular guideway actuates the push rod, and hence the valve. The segmental element may include an oil reservoir which receives oil from a duct or reservoir in the casing or flanges, and conducts the oil to an oil duct in the push rod.

摘要： In a fuel injection pump for internal combustion engines, a reciprocable piston injects fuel on each compression stroke. The cylinder in which the piston reciprocates has an overflow port which is controlled by at least one control edge of the piston so as to effect injection during the portion of the compression stroke when the overflow port is closed. The beginning and/or end of injection are variably regulated relative to the compression stroke by a setting member which varies the stroke of the piston relative to the overflow port, and hence the elapsed time between the beginning of the compression stroke and the beginning and/or end of the injection.
摘要翻译：在用于内燃机的燃料喷射泵中，可往复运动的活塞在每个压缩行程上喷射燃料。活塞往复运动的气缸具有由活塞的至少一个控制边缘控制的溢流口，以便当溢流口关闭时在压缩冲程的该部分期间实现喷射。注射的开始和/或结束通过改变活塞相对于溢流口的冲程的设定构件相对于压缩行程可变地调节，因此压缩冲程开始与开始之间的经过时间和/ 或注射结束。
