Description
Technical field
The utility model belongs to turbo-charger technical field, more particularly, relates to a kind of turbocharger air compressor end sealing configuration.
Background technique
At present, increasing passenger car motor has adopted turbocharging technology.Turbosupercharger relies on the engine exhaust energy, ambient air is compressed in the cylinder fuel oil and air mixing after-combustion and outputting power through the rotor high-speed rotation.Because the vehicular engine operating mode is complicated, under some operating mode (such as engine start time), the engine exhaust energy shortage, the turbocharger rotor rotating speed is lower, and this moment, the gas compressor end pressure of turbosupercharger was lower than the middle case internal pressure.If do not take the effective seal measure, a large amount of lubricant oil will be scurried into gas compressor and get into the motor internal combustion in the middle case under the pressure difference effect, cause one side engine lubrication oil consumption excessive, and lubricant oil burning generation blue smoke is unfavorable for discharging on the one hand.In addition, a large amount of lubricant oil flow into the compressor impeller wheel back of the body, make gas compressor play the oil pump effect, are used for pump to the part useful energy and inhale lubricant oil, have reduced the efficient of gas compressor.Solving gas compressor end leakage of oil problem starts with from following two aspects usually: 1. create favourable pressure balance, promptly guarantee turbosupercharger under various operating modes, the pressure at compressor impeller wheel back of the body place is higher than the pressure in the middle case oil pocket all the time.2. take the effective seal measure.Patent 01251885.9 prevents the leakage that pressure difference causes through the pressurized gas at blower outlet place are introduced piston ring near gas compressor one side.This scheme deficiency is to have consumed a part of pressurized air, and sealability is stable inadequately, and sealing effect is not remarkable when boost pressure is not high enough.Patent 03212679.4 thinks, the opening on the piston ring is the approach that leaks, and therefore proposes to adopt astomous piston ring to solve leakage problem, if but the endoporus interference fit of piston ring and ring installation then piston ring can not rely on end face to seal when working; If Spielpassung then piston ring can not rely on external cylindrical surface to seal.Patent 03235974.8 and 200610042018.3 proposes to adopt piston ring, the thrust sleeve of special shape, the combination seal mode of oil baffle.These two kinds of schemes are the more schemes of implementing at present, but the partial rotation part structure that relates to is complicated.
