摘要

A. VACUUM PILOT SWITCH, ESPECIALLY FOR PILOT AN EXHAUST GAS VALVE FOR INTERNAL COMBUSTION ENGINES. / P P B.A VACUUM PILOT VALVE IS FASTENED TO THE PUMP. INJECTION 10 OF THE DIESEL ENGINE AND IT IS MANEUVERED BY ITS TREE 23 RELATED TO THE ACCELERATOR. IT HAS A DOUBLE SEAT VALVE 33, 44, 43 THAT MANEUVER A PAIR OF CAM RINGS 50, 60. ONE OF THE CAM RINGS 50 IS FIXED IN THE CARTER AND FLANGES THE EDGE 42 OF A MEMBRANE TO DEROULER 41 OF WHICH THE MEDIAN PART IS SHUTTER 43 AND HOLDING A PISTON 45 HAVING A VALVE SEAT 44. THE OTHER CAM RING 60 CAN TURN AND SLIDE AXISELY IN THE FIXED RING AND ACTS ON THE PISTON THAT CARRYS THE MOBILE VALVE SEAT. / P P C. THE INVENTION CONCERNS THE RETURN OF EXHAUST GASES INTO A DIESEL ENGINE. / P
