Embodiment

[0018] Such as figure 1 As shown, a turbulent, anti-deformation, and valve-free intake valve connecting device mainly includes a valve head 2, a valve stem 3, a spring seat 8, a spring 5, an elastic pad 7 and a valve sleeve 4. The valve head 2 and the valve stem 3 are integrated. The valve stem 3 is equipped with a spring seat 8. The spring seat 8 has a disc-shaped structure. The spring seat 8 has a protrusion on the edge, an internal threaded hole in the middle of the outer side, and a threaded hole in the middle of the inner side. The outer threaded cylinder is matched with the inner threaded hole of the valve head 2; the upper end of the spring seat 8 is equipped with an elastic pad 7 and the lower end is installed with a spring 5, the springs 5 ​​are 4 and are evenly distributed in the circumferential direction, and the spring 5 is fixed on the cylinder wall 1; 4 is installed outside the valve stem 3.

[0019] The valve stem 3 is equipped with two sets of vertically staggered...

Abstract

The invention provides a flow-disturbing, deformation-proof and valve-free intake valve connecting device, which mainly includes a valve head, a valve stem, a spring seat, a spring, an elastic pad and a valve cover. Its characteristic is that the valve head has the function of turbulence, the valve stem is high-strength and anti-deformation, and there is no valve gap between the valve and the rocker arm. The present invention has the functions of increasing air intake, guiding fluid and generating vortex through the protruding ring with a parallelogram-shaped section on the valve head and inwardly inclined; Constant fan steel rods are used to strengthen the strength of the valve stem and restrain its expansion; through the elastic pad of high elastic rubber material, the zero clearance of the valve is realized; through the valve cover of aluminum alloy material, the rapid heat dissipation of the valve stem is realized; through the constant fan steel clip The ring suppresses expansion deformation of the valve cover.

Description

Technical field [0001] The invention relates to a turbulent, anti-deformation and valve clearance-free intake valve connecting device, in particular to a convex ring whose cross-section on the valve head is parallelogram and inclined inward, so as to increase the intake air volume, The function of guiding the fluid and generating the vortex; through the vertical staggered horizontal and vertical constant steel bars on the valve stem, the strength of the valve stem is strengthened and the expansion is suppressed; the valve is realized by the elastic cushion of high elastic rubber material The zero clearance of the valve; the rapid heat dissipation of the valve stem is realized by the valve sleeve of aluminum alloy; the expansion and deformation of the valve sleeve is suppressed by the Hengfan steel snap ring, which belongs to the technical research and development field of engine valves. Background technique [0002] The function of the engine intake valve is to draw air into the ...
