The hydraulic system has the advantages of being capable of fast reaching the working position and fast resetting, and being stable and reliable in operation, long in service life, reasonable in design, simple in structure, remarkable in energy saving effect, and high in automation degree and working efficiency.
Description
Technical field
The utility model relates to a kind of hydraulic system, is specifically related to a kind of internal-combustion engine with light-load energy saving organization hydraulic pressure system.
Background technique
Along with the sharply increase of automobile and engineering machinery vehicle quantity, current vehicle day by day becomes the common problems of concern in countries in the world to the pressure that the energy and environment cause.When sliding, the control engine oil supply system is fuel feeding and utilize hydraulic pressure installation positive opening engine exhaust port not at automobile, reduces motor forced idling oil consumption and engine exhaust resistance, and coasting distance is increased, thereby reaches the purpose of energy-saving and emission-reduction.Simultaneously, this device is ineffective rapidly when braking, and the engine exhaust resistance recovers rapidly, and this moment, motor and break were braked simultaneously, had guaranteed traffic safety.
The model utility content
The purpose of this utility model is to reach above-mentioned technical requirements, provide a kind of internal-combustion engine with light-load energy saving organization hydraulic pressure system, but it can reach working position and returning quickly fast, stable and reliable operation, long service life, reasonable in design, simple in structure, energy-saving effect is remarkable, and automaticity is high, high working efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of internal-combustion engine is with light-load energy saving organization hydraulic pressure system, comprise oil hydraulic pump, it is characterized in that: described oil hydraulic pump outlet is communicated with solenoid directional control valve one P mouth, described solenoid directional control valve one Q mouth is communicated with the rodless cavity of oil hydraulic cylinder one, oil hydraulic cylinder two, oil hydraulic cylinder three and oil hydraulic cylinder four, described solenoid directional control valve one Q mouth is communicated with solenoid directional control valve two S mouths, and described solenoid directional control valve two R mouths are communicated with fuel reserve tank.
Above-mentioned internal-combustion engine is characterized in that with light-load energy saving organization hydraulic pressure system: described oil hydraulic pump outlet port is provided with relief valve.
Above-mentioned internal-combustion engine use light-load energy saving organization hydraulic pressure system, it is characterized in that: described solenoid directional control valve one and described solenoid directional control valve two are two two electric change valves.
The utility model compared with prior art has the following advantages:
(1) this internal-combustion engine can make light-load energy saving mechanism reach fast the working position and can make its returning quickly with light-load energy saving organization hydraulic pressure system.
