The supercharged engine that has closure, particularly petrol engine adopts supercharging technology when its work, behind accelerator pedal, unclamp suddenly, the blower outlet of turbosupercharger is to the volume that can form an approximate sealing between the closure suddenly, and the impeller in the gas compressor is because the effect of rotatory inertia is still imported suction tude with pressurized air.At this moment, compressor delivery pressure rises, and air mass flow reduces, and very easily causes turbo-charger surge.The approach that solves is to adopt the Decompression valves that is installed on the compressor volute to control compressed-air actuated backflow at present, avoids causing turbocharger surge owing to too much pressurized air enters suction tude.
Existing Decompression valves adopts the mechanical type Decompression valves usually, is installed on the compressor volute, directly gets gas behind closure, and the control mode of mechanical type Decompression valves is that its setting value is approximately a definite value by pressure reduction control.Because its setting value is approximately a definite value, its pressure reduction control can't be regulated at each operating mode, in use following situation can occur:
One, motor is in that middle and high fast operating point is anxious when slowing down, closed throttle, and what the unlatching of mechanical type Decompression valves need be set up a higher pressure value could complete opening, can produce induction noise when valve is not exclusively opened, and surge takes place easily, occurs uttering long and high-pitched sounds.
Two, motor is when suddenly slowing down the back speed-raising, because the delay of mechanical type Decompression valves is corresponding, valve fails in time to close, cause the compressor characteristics of turbosupercharger in time not recover, instantaneous correspondence is poor, is easy to generate pneumatic noise simultaneously, and the speed-raising performance of vehicle and travelling comfort are reduced.

During use, be installed on the compressor volute automatically controlled Decompression valves is integrated, adopt the electronic type control mode to link to each other, control opening and closing of exhaust passage by the on/off valve with ECU.
Automatically controlled Decompression valves control principle provided by the invention is as follows:
One, when gasoline supercharged engine during in proper functioning, automatically controlled Decompression valves is in closed condition, this moment, the piston sleeve of automatically controlled Decompression valves stretched out downwards, bleed valve aperture of door on the pressurized machine is closed, the pressurized air of gas compressor compression all enters cylinder, and the compressor characteristics of turbosupercharger do not change.
Two, when the gasoline supercharged engine under anxious decelerating operation, closed throttle, blower outlet in turbosupercharger is similar to the volume that seals to forming one suddenly between the closure, compressor delivery pressure continues to rise, ECU sends start signal for rapidly automatically controlled Decompression valves according to the rate signal (or suction pressure transducing signal of engine intake manifold) of accelerator pedal displacement sensor passes.After automatically controlled Decompression valves is received the unlatching electrical signal, the coil winding energising, under the effect of static iron core, produce and add high magnetic fields, moving iron core overcomes spring under the suction in magnetic field spring force moves upward, thereby driving piston sleeve moves upward together, be present in the air between baffle plate and the piston sleeve, discharge, can not have side effects magnetic field suction by the relief hole on piston sleeve and the lower shell body.Stop when moving to confined planes, the bleed valve aperture of door is opened, this moment, automatically controlled Decompression valves was finished unlatching, and excess gas is discharged from airflow hole.
Three, when motor raises speed the recovery conventional operation in the anxious back of slowing down, ECU can in time send electrical signal to automatically controlled Decompression valves according to the rate signal (or suction pressure transducing signal of engine intake manifold) of accelerator pedal displacement sensor passes, the coil winding outage, the high magnetic fields that adds that static iron core produces disappears, moving iron core drives piston sleeve and moves downward together under the spring force effect of spring, piston sleeve is closed the bleed valve aperture of door rapidly.
