JPS62199914A - Rotary valve for internal combustion engine - Google Patents

Abstract

PURPOSE:To achieve the smooth function of a valve by providing valves having a hole through the shaft thereof between an intake hole of a cylinder head and a combustion chamber, and between a discharge hole and the combustion chamber and rotating the shaft synchronously with the rotation of an engine. CONSTITUTION:Valves 2, 4 are arranged at the cylinder head section above a cylinder 5 respectively at such portion as communicating between an intake hole 1 and the interior of the cylinder 5 and the portion communicating between a discharge hole 3 and the interior of the cylinder 5. The valves 2, 4 have such shape as a hole is made through a tubular shaft, and when said shaft type valves are rotated synchronously with the rotation of engine, the functions of an intake valve and a discharge valve can be achieved.

Description

[Detailed Description of the Invention] 6.Detailed Description of the Light This invention has a T bar (-, H) that rotates the valve device between the internal combustion and L sections.

The inside of the robe was opened and closed by the movement of the shogun and the shogun. Tokoroge The reciprocating valve is limited to the shape (the size of the valve is 1J combustion chamber /) as it was born in the Ochuyaki family (2 times!
