Rotation, piston 1.2 move downward (power input shaft rotates angle from 90 ° to 270 ° of progressive formations), gas after having crossed extreme higher position
Room volume become larger to be formed vacuum hinder piston 1.2 move downward, to power input shaft 1.9 provide the work of resistance, provide system for vehicle
Power, for gas chamber volume in approaching maximum process, intake valve 1.6 opens (being near 270 ° in power input shaft rotation angle),
Air in atmosphere enters gas chamber, closes in gas chamber full of intake valve 1.6 after air, makees in the driving of the power output end of vehicle
With lower power input shaft 1.9 as the rotation of transmission shaft 10 continues to rotate, piston 1.2 moves upwards after having crossed extreme lower position.
An above-mentioned working cycles for vapour-pressure type retarder 1, by constantly recycle provided for vehicle it is continual
Additional braking force.Buffer controller 3 according to the angular sensor signal of power input shaft, calculate exhaust valve 1.5 and into
The opening and closing opportunity of air valve 1.6 and opening and closing duration, guarantee that vapour-pressure type retarder 1 provides maximum auxiliary braking power.
When buffer controller 3 judges that vapour-pressure type retarder 1 needs to stop working, buffer controller 3 issues signal
It requests clutch 8 to separate, stops that clutch 8 is carried out to control to keep it in discrete state, stop to exhaust valve 1.5 and air inlet
Valve 1.6 is controlled, and normally off is kept it in.
More than, only a specific embodiment of the invention, it is noted that it is the prior art that remaining is unspecified, is appointed
