Abstract
Description
Technical Field
[0001] The utility model belongs to the field of automobile relay valves and relates to an automobile relay valve. Background Art
[0002] When a car is in use, the water vapor generated by the air compressor, as well as moisture and dust particles in the atmosphere, enter the relevant valve body assembly, affecting various components in the air brake system. After a long time, a large amount of impurities and rust substances are generated, thereby affecting the cleanliness of the vehicle pipelines and, in severe cases, the braking performance of the vehicle.
[0003] The Chinese utility model patent with the patent number ZL200720311691.2 discloses a controllable actuation relay valve, which is provided with a filter at the air inlet, effectively reducing the entry of impurities such as water vapor and dust into the valve body, and improving the cleanliness of the entire vehicle pipeline. However, since the air inlet channel is very small and the effective area of the filter is also very small, when used in a relatively harsh environment, it is very likely that the filter will be partially or completely blocked, causing unstable airflow at the air inlet, thereby causing serious situations such as braking delay and insufficient braking force; and since the space between the air inlet and the filter is narrow, the filter is also very difficult to assemble during installation.
