Document Type and Number:
Japanese Patent JPS6131123
Kind Code:
Y2
Abstract:
A sealing structure of a rotary valve in an internal combustion engine in which a recess is formed either at an opening portion of a rotary valve proper or at an opening portion of a combustion chamber in a housing and in which a seal member slidably fitted in the recess is resiliently pushed against the opposing part by means of a spring member. An annular resilient member is interposed between the lower surface of the seal member and the opposing bottom surface of the recess in such a manner that the two ends of the resilient member are respectively in contact with the surfaces of the seal member and the recess. Thereby, the contact pressure at the ends of the resilient member is increased by utilizing the gas pressure in the combustion chamber. Further, the pushing force of the seal member against the opposing part is increased, so as to enhance sealing efficiency.
