Sealing air supplying device for effective turbine of internal combustion engine of vehicle, has collar cooperating with valve seat, which locks passage between chambers when predetermined pressure attains sealing air in one of chambers

摘要

The device has a pressure limiting valve (13) comprising a chamber (27) connected with a magnet valve, and another chamber (33) connected with a hollow space (12). The valve has a piston (28), which is displaceably loaded by a spring (29) and is arranged in the chamber (33). The piston with a piston rod (28a) extended into the chamber (27), and the piston rod stays in contact with a collar (30) arranged in the chamber. The collar cooperates with a valve seat (35), and locks a passage (34) between the two chambers when a predetermined pressure attains sealing air in the chamber (33).
