TH45114B - Internal combustion engine and structure for stimulating the tongue - Google Patents

Abstract

DC60 (12/06/57) The valve operating structure for the internal combustion engine with water pump is Held tightly on the camshaft, which is fitted with a pressure relief device, so This makes the cylinder head able to be built into a smaller size. A valve operating structure for the internal combustion engine will be installed. It is equipped with the camshaft 53 and the exhaust valve 56e which has been opened and closed by the 53e exhaust cam provided on the 53 camshaft and the 100 pressure reducer 101 for the actuation of the damping cam Push 105 that can extend / retract from the cam surface of the cam For the operation of the tongue, the 53e is supported in such a way that it can move around by Centripetal force at or near the end of the camshaft 53 Water pump 120 will be positioned at One end of the camshaft 53 on the opposite side is the pressure reducing weight 101 in the axial direction. The operating structure of the tongue for the internal combustion engine with water pump is Held tightly on the camshaft, which is fitted with a pressure relief device, so This makes the cylinder head able to be built into a smaller size.
