Abstract

The invention provides an inlet valve connecting device with the vortex generation function and without a valve clearance. The inlet valve connecting device mainly comprises a valve head, a valve rod, a valve sleeve, a snap ring, a spring seat, drive springs, a vortex generation device and a buffer device. The inlet valve connecting device is characterized in that a vortex can be generated by a valve and no valve clearance exists. Through a pit and inclined holes in the valve head, the air inflow is increased, inflation efficiency is improved, the vortex is generated, and it is guaranteed that combustible mixed gas is fully burnt in time; through buffer springs on the spring seat and a buffer seat, no valve clearance exists; through the aluminum alloy valve sleeve, the heat of the valve rod is rapidly dissipated; and through the invar steel snap ring, expansion deformation of the valve sleeve is restrained.

Description

technical field [0001] The invention relates to an intake valve connection device capable of generating eddy currents and having no valve clearance, in particular to a device for increasing the intake air volume, improving the charging efficiency, generating eddy currents, and ensuring flammability through the pits and oblique holes on the valve head. The mixed gas is combusted in time and fully; through the buffer spring and buffer seat on the spring seat, no valve clearance is realized; the rapid heat dissipation of the valve stem is realized through the aluminum alloy valve cover; the expansion deformation of the valve cover is restrained by the constant range steel snap ring, which belongs to The field of technology research and development of engine valves. Background technique [0002] The role of the engine intake valve is to draw air into the engine and mix it with fuel for combustion. However, due to the singleness of the current intake valve structure, the followi...
