Non-return valve, especially in motor vehicle heating system, has tubular sleeve housing inserted into, held in hydraulic system line or connector or whose diameter matches line/connector

摘要

The heating system has a heat exchanger thermally coupled to heat sources via a heat carrying medium circuit, especially a water circuit. Pumps control the heat carrying medium flow in large and small circuits in two states. The valve has a housing in the form of a tubular sleeve that is inserted into and held in lines or connectors in the hydraulic system, or whose diameter matches the lines or connectors so that it can be inserted and held. The heating system has a heat exchanger (1) acting as a heating body and thermally coupled to heat sources (3,4) via a heat carrying medium circuit, especially a water circuit. Pumps (7,8) control the flow of heat carrying medium in large and small circuits in two states. The non-return valve (9) has a housing in the form of a tubular sleeve that is inserted into and held in lines or connectors (17) in the hydraulic system, or whose diameter matches the lines or connectors so that it can be inserted and held.
