Patent DE-3108813-A1 (DE)
Title: Cylinder head for 4-stroke engines through which air flows, at which has a single valve and is slide-valve controlled
Inventor: VOSS PETER
IPC: F01L1/28
Filed: 1981-03-09
Abstract: In order to obtain good efficiency in internal combustion engines, a compact combustion chamber (which permits a high compression), large inlet and exhaust cross-sections, low mechanical stressing and good swirling are needed. In our principle, this is achieved in that the combustion chamber is opened and closed by only one valve. The primary control is performed by way of a control sleeve running round the valve, which is driven by the camshaft at the same rotation speed. When clean air is drawn in, that is to say direct injection, in the rotating control sleeve a spin is imparted to the air flow, which ensures good swirling during compression. At the top dead centre piston position the control sleeve, the inlet and exhaust always overlap, so that air flows through the cylinder head, thereby ensuring a thermal balance with simultaneous improvement of the exhaust quality. A diaphragm in the inlet further improves the charge. This control principle is suitable for all 4-stroke engines, especially in conjunction with turbochargers.

Patent DE-3211095-A1 (DE)
Title: Hydraulic belt tensioner
Inventor: KODAMA HISASHI
IPC: F16H7/08
Filed: 1982-03-25
Abstract: The belt tensioner comprises a lever pressed against a belt and a hydraulic jack with a piston pressed against the lever by a return spring. Formed between the piston and its housing is a pressure chamber in which there is hydraulic fluid. In the case of an upward movement of the piston in the direction of the force of the return spring, a nonreturn valve opens the connection between the pressure chamber and a reservoir chamber in the piston. In the case of a downward movement of the piston, the hydraulic fluid can only escape from the pressure chamber along a highly restricted leakage path. When the idle strand against which the belt tensioner rests becomes the working strand during operation, the jack yields only gradually, allowing this changeover of the belt drive to take place without a delay.
