Abstract
The utility model relates to an automotive accessory, in particular to a simple taper steering pump which comprises a pump body, a valve core spring, a valve core assembly, a nozzle tip and an O-shaped ring, wherein a valve body is arranged on the pump body, the valve core spring, the valve core assembly, the O-shaped ring and the nozzle tip are arranged in the valve body in turn, one end of the valve core spring is pressed on the bottom of the valve body, and the other end thereof is pressed on the valve core assembly, the other end of the valve core assembly is pressed on the nozzle tip, the nozzle tip is fixedly arranged on the opening of the valve body, and the O-shaped is arranged between the nozzle tip and the valve core assembly. The structure changes a traditional slide plug control structure, the nozzle tip with a taper oil way is directly adopted, the quantity and the stability of flow are controlled through the rate of the taper and small hole of the nozzle tip oil way, therefore, the structure is simpler, the control is convenient, and the flow can be set only by setting the fixed rate of taper and small hole.
Description
Technical field
The utility model relates to a kind of auto parts machinery, especially a kind of simple and easy tapering steering pump.
Background technique
Power steer is to utilize external impetus to assist the device of the light operation steering wheel of driver.Along with the increase of nearest motor car engine horsepower and the generally use of flat tire, car weight and steering drag have all been strengthened, so servosteering mechanism is more and more universal.It should be noted that power steering should not be constant, because when running at high speed, the lateral resistance of tire is little, and it is light that steering wheel becomes, and be difficult to catch the sensation on road surface, also causes easily to turn to too sensitive and make automobile wayward.
Steering pump is an accessory very important in the power steer, traditional steering pump comprises the pump housing, valve core spring, Spool assembly, spring housing, sliding plug, sliding plug spring, oil nozzle, O type circle, because this steering pump is to utilize sliding plug to come control flow rate, but such control mode requires very high to sliding plug spring, and be difficult to control, requirement to sliding plug is also very high, the particularly tapering of sliding plug and the control of length, and such infrastructure product quality is to be difficult to guarantee.
Summary of the invention
The purpose of this utility model is, a kind of simple in structure, control is simple, stability is high simple and easy tapering steering pump is provided.
The utility model is to realize by following scheme: a kind of simple and easy tapering steering pump, comprise the pump housing, valve core spring, Spool assembly, oil nozzle, O type circle, the pump housing is provided with valve body, valve core spring, Spool assembly, O type circle, oil nozzle are successively set in the valve body, one end of valve core spring withstands the valve body bottom, and the other end withstands Spool assembly, it is characterized in that the other end of Spool assembly withstands oil nozzle, oil nozzle is fixedly installed on the valve port of valve body, is provided with O type circle between oil nozzle and the Spool assembly.
Of the present utility modelly further be set to: the oil duct of described oil nozzle inside is a funnel form.
Said structure has changed traditional sliding plug control structure, directly adopt the oil nozzle that is provided with the tapering oil duct, utilize the ratio of the tapering of oil nozzle oil duct and aperture to come the size and the stability of control flow rate, like this relatively simple for structure, and control easily, as long as fixing tapering is set and the aperture ratio is set flow.
