FLOW CASING FOR AN OIL VALVE

摘要

A flow casing for an oil valve includes a supporting housing comprising a supporting bore. A valve housing is arranged in the supporting bore. A first bore and a second bore are arranged in the valve housing. A first connectable nozzle and a second connection nozzle are each formed in the supporting housing and are each fluidically connectable. The first connectable nozzle is fluidically connected to the first bore. The second connection nozzle is fluidically connected to the second bore. At least one peripheral surface is arranged on the valve housing axially between the first bore and the second bore. The at least one peripheral surface comprises a first groove. A first seal ring is arranged in the first groove on the at least one peripheral surface. The thermal expansion coefficient of the first seal ring is higher than the thermal expansion coefficient of the supporting housing.
