1results about How to "Efficient buffering" patented technology

This utility model provides an oil filter pressure reducing valve, including a filter connecting plate, a main housing, and an outer housing. The main housing and the outer housing are fixed to the lower end of the filter connecting plate. The main housing is located inside the outer housing, and an auxiliary cavity is formed between the main housing and the outer housing. A sealing block is fixed to the lower end of the auxiliary cavity. A second filter ring and a first filter ring are respectively embedded at the upper and lower ends of the outer housing. The main housing has a main cavity, and a fixing plate is horizontally welded inside the main cavity. This design solves the problem that the original oil filter pressure reducing valve actually uses a single spring for pressure reduction, resulting in poor pressure reduction effect after long-term use. This utility model adopts a double-spring pressure balance and magnetic damping composite structure, which can efficiently buffer the oil fluid. The use of the main cavity and auxiliary cavity structure makes this pressure reducing valve more precise.
