After using a period of time, the impurity that produces in fuel tank production and the using process, metal fillings and the impurity in the fuel oil that this oil channel structures stays in gold machining will deposit in chamber gradually, the valve block of one-way valve is blocked, cause malfunctioning, the blow-by of one-way valve, like this, pump low on fuel or pump oil condition not can often appear in hand oil pump, thus hand oil pump malfunctioningly happens occasionally, can't proper functioning, bring inconvenience for user's use.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of hand oil pump oil way improved structure of guaranteeing the lasting proper functioning of hand oil pump.
For solving the problems of the technologies described above, hand oil pump oil way improved structure of the present invention comprises oil inlet pipe, oil outlet tube reaches and interconnects the back up and down to form the pump cover of chamber, filter block, the diapire of chamber is provided with in line check valve and fuel-displaced one-way valve, downside with respect to pump cover on the filter block is groove hole, oil inlet passage is arranged in the filter block, oil discharge passage, the joint passage, the outer end of oil inlet passage is positioned on the sidewall of filter block and is lower than chamber, the outer termination oil inlet pipe of oil inlet passage, the roof in groove hole has a through hole that communicates with the inner of oil inlet passage, one end of oil discharge passage makes chamber communicate with oil discharge passage by fuel-displaced one-way valve, the other end is positioned on the sidewall of filter block and is lower than chamber, the other end of oil discharge passage picks out oil pipe, the upper end of joint passage makes the joint passage communicate with chamber by in line check valve, the lower end is the inipple of hollow, and inipple exceeds filter block through the groove hole.
Have hand oil pump that this oil circuit the improves structure thread plate sub-assembly by inipple and existing filter cleaner and spin, oil inlet pipe, oil outlet tube are connected in the oil circuit of used in fuel oil system of motor-driven vehicle, and hand oil pump can use.
Be used for describing beneficial effect of the present invention below by introducing specifically making of hand oil pump:
When hand oil pump initialization and filter cleaner proper functioning, fuel oil in the fuel tank enters in the filter cleaner and filters earlier and water separation through oil inlet pipe, oil inlet passage, through hole, groove hole, the clean fuel oil of gained enters in the chamber through inipple, joint passage, in line check valve again, at last, clean fuel oil flows out (being that fuel oil is earlier through filter cleaner, pass through one-way valve and chamber again) through fuel-displaced one-way valve, oil discharge passage, oil outlet tube.
Like this, fuel oil in the fuel tank filters earlier and water separation (impurity that is about in the fuel oil is trapped in the filter cleaner), just flow through inipple, joint passage, in line check valve, chamber, fuel-displaced one-way valve, oil discharge passage, oil outlet tube of the clean fuel oil of gained then, avoided impurity in chamber, to deposit gradually, the valve block of one-way valve can not blocked, make one-way valve sealing effect better, can not be malfunctioning.
In sum, the functional reliability of hand oil pump is improved (can often not occur pump low on fuel or not pump oil condition), has guaranteed the lasting proper functioning of hand oil pump, brings many convenience for user's use.
