Product Parameter

The Role of the Engine Valve Spring Retainer

The valve seat is the part where the intake and exhaust ports of the cylinder head fit with the valve cone surface. The function of the valve seat is to seal the cylinder together with the valve head, and at the same time receive the heat from the valve head to dissipate heat to the valve.

The valve seat can be directly bored on the cylinder head, or a seat ring (called a valve seat ring) can be made of heat-resistant alloy steel or alloy cast iron and pressed into the cylinder head (body). This kind of valve seat ring has the characteristics of high temperature resistance, wear resistance, impact resistance, long service life and easy replacement after damage, so it is widely used in modern engines.

Due to the large thermal load of the valve seat ring, the large temperature change, and the impact of the valve seat, in order to prevent falling off and good heat dissipation, the valve seat and the seat hole should have high machining accuracy and low surface roughness. and larger fit interference. When assembling, it should be noted that the temperature difference method is used to press in.

Product Application

Cummins engines are mainly used in commercial vehicles, construction machinery, mining equipment, marine power and generator sets, etc.
