Radiator Cap

摘要

PURPOSE: A radiator cap is provided to maintain the uniform inside pressure of a radiator by keeping the flow of cooling water and air smooth. CONSTITUTION: A radiator cap comprises a pressure valve(110) and a negative pressure valve(120). The pressure valve is inserted within a cooling water inlet of a radiator and has a through-hole(111) on the bottom surface. The pressure valve opens and closes an inlet port(10) controlling the inner pressure of the radiator. The negative pressure valve comprises a valve stem and a combining member. The valve stem opens and closes the through-hole of the pressure valve controlling the inner pressure of the radiator. A flow groove is formed on the side of the combining member. The combining member is formed in a bundled structure.
