Electromagnetic valve controller for controlling gas shuttle valve of combustion engine, has pressure disks whose velocity and acceleration are set based on annular gap dimension such that air pressure is escaped from cylinder housing

摘要

The controller has electromagnetic actuators (1,40) having actuator housing (9) in which brake cylinder housings (2,31) with ventilation openings (5,7,27,34) are provided. The ventilation openings are hermetic sealed with slide bearing (23). The brake cylinder inner walls (25,38) of cylinder housing are not physically contacted with pressure disks (4,33) through annular gaps (26,39). The velocity and acceleration of pressure disks are set based on dimension of annular gap such that air pressure is escaped from cylinder housing through air pressure outlet valve (28).
