Direct acting safety valve and reciprocating piston combustion engine with this safety valve

摘要

The direct acting safety valve is controlled by the valve housing (1), valve seat (36), valve body (2), valve spring (5) that generates a seating force irrespective of the pressure of the medium, and pressure of the medium. A hollow body 3 which can be compressed and connected to the valve body 2 to generate a seating force in accordance with the pressure of the medium, and a second valve spring 7 for setting blowoff pressure. Due to the seating force generated by the pressure of the medium, a small seat area can be formed, so that the valve is driven at a precisely defined medium pressure.
