AI Technical Summary

Technical Problem

In existing exhaust valves, the space between the moving iron and the stationary iron is small, resulting in unresponsive operation and easy freezing in cold areas, which affects the movement of the moving iron and causes the valve core to malfunction.

Method used

An elastic reset element and a sealing ball are configured between the moving iron and the sealing head. The through hole design ensures that the air between the moving iron and the stationary iron can be smoothly discharged, and a sealing structure is set at the through hole to prevent cold air from entering and avoid freezing.

Benefits of technology

This design achieves rapid response of the exhaust valve and smooth movement of the moving iron, avoiding icing problems caused by cold air entering and ensuring the normal operation of the exhaust valve.

Abstract

This invention discloses an exhaust valve and an air suspension system and automobile having the same, relating to the field of air suspension technology. It includes a housing, a moving iron, a stationary iron, a valve body, and a sealing head. The moving iron and stationary iron are mounted axially within the housing. The valve body is installed at the opening of the housing. The sealing head is connected to the moving iron. A first through hole and a second through hole are respectively provided on the moving iron and the sealing head. The first through hole connects the second through hole to the gap between the moving iron and the stationary iron, and the second through hole communicates with the exhaust port. An elastic reset member and a sealing ball are connected between the moving iron and the sealing head. The elastic reset member abuts the sealing ball against the first through hole, blocking both the first and second through holes. When the moving iron moves towards the stationary iron, the air between the moving iron and the stationary iron can push the sealing ball, thus opening the first and second through holes. The beneficial effect of this invention is that it can prevent external air from entering between the moving iron and the stationary iron and causing icing.
