Abstract
The invention discloses a spring bottom seat on diesel engine high-pressure pumps. The spring bottom seat comprises a seat body formed by a cap and a column, and a plunger mounting seat is formed in the column. The spring bottom seat is characterized in that a tapered hole is formed in the end of the cap. The tapered hole contacting with a roller is formed, so that the end of the seat body is avoided being directly pressed by the roller, the situation that the roller is stuck and cannot rotate is avoided, and the spring bottom seat is mainly used on the diesel engine high-pressure oil pumps.
Description
Technical field
The present invention relates to high-pressure fuel pump of diesel engine technical field, the spring lower seat on especially a kind of high-pressure fuel pump of diesel engine.
Background technique
The spring lower seat of conventional diesel engine high pressure oil pump is for being set with piston spring, in the process of real work, roller can be pressed in the pedestal end of spring lower seat, pedestal end due to the spring lower seat of transmission is plane structure, cause roller to be directly pressed in pedestal end, often the stuck phenomenon that cannot rotate of roller occurs.Therefore, design a kind of spring lower seat that can solve the problem well to be extremely necessary.
Summary of the invention
Object of the present invention is improved for above-mentioned the deficiencies in the prior art exactly, provides the spring lower seat on a kind of high-pressure fuel pump of diesel engine.
Concrete scheme of the present invention is: the spring lower seat on a kind of high-pressure fuel pump of diesel engine, has pedestal, and pedestal is made up of cap body and cylinder, cylinder has plunger mounting groove; It is characterized in that: described cap end of body has a cone shape hole.
The body of cap described in the present invention is rounded, and its diameter D is 40mm.
The present invention has cone shape hole, and roller is not directly pressed in pedestal end, but rolls with cone shape hole and be connected, and effectively can avoid that roller is stuck cannot rotate, and the stability of use improves greatly.
Accompanying drawing explanation
Fig. 1 is main sectional view of the present invention;
Fig. 2 is the perspective view at the present invention first visual angle;
Fig. 3 is the perspective view at the present invention second visual angle.
In figure: 1-cone shape hole, 2-cylinder, 3-plunger mounting groove, 4-cap body.
Embodiment
