  • Valve arrangement for a combustion engine
    Patent number: 6953018
    Abstract: The invention is related to an arrangement that is designed to control inlet and outlet gas mixtures and is used mainly in four stroke combustion engines. Prior art designs are of a kind that limits the performance of the four-stroke engine mainly as a result of the weight and its flow-technical design. The invention resolves this problem by providing a valve design that allows both the inlet and outlet gas mixtures to flow inside and through the valve body, which facilitates a valve design that is lighter and has an higher efficiency due to the flow-technical aspects, e.g. eliminating any valve shaft obstructing the flow path.
