Abstract
The utility model discloses a kind of fuel tanker and exempt from quick change fuel pump of draining the oil, comprise pump outer cover, impeller, snail chamber and Outlet check valves, oil circuit between the snail chamber and Outlet check valves of pump is provided with exhaust valve, and the valve lid of described exhaust valve is made by elastomeric material.Described valve lid is made up of elastomeric material.The utility model has exempts to drain the oil and have self-bleeding advantage.
Description
Technical field:
The utility model relates to a kind of pump, and particularly a kind of fuel tanker exempts from quick change fuel pump of draining the oil.
Background technology:
Existing exempt to drain the oil quick change fuel pump due to installation site higher, and outlet is provided with one way stop peturn valve, easily vent plug occurs during pump startup, and causing can not normal fuel injection, and solving vent plug problem is take housing unit tube connector apart to be manually vented, time-consuming and reliability is poor.
Summary of the invention:
The utility model object is that design one is exempted to drain the oil and self-bleeding a kind of fuel tanker exempts from quick change fuel pump of draining the oil.
The technical solution of the utility model is that a kind of fuel tanker exempts from quick change fuel pump of draining the oil, comprise pump outer cover, impeller, snail chamber and Outlet check valves, it is characterized in that: on the oil circuit between the snail chamber and Outlet check valves of pump, be provided with exhaust valve, the valve lid of described exhaust valve is made by elastomeric material.Described valve lid is made up of elastomeric material.
The utility model has compared with the prior art exempts to drain the oil and have self-bleeding advantage.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
The utility model has following embodiment, and the snail chamber 6 in pump outer cover 1 and the oil circuit 5 between Outlet check valves 8 are provided with exhaust valve 7, and this exhaust valve is made up of valve base and rubber valve lid.
Operation principle of the present utility model is, when there is vent plug, when oil feed pump starts to engine oil, if produce vent plug in oil circuit, fuel pump impeller 3 rotates, the gas boosting in snail chamber, and exhaust valve is opened, air scavenge in snail chamber, just can to engine oil, when dismounting pump core, exhaust valve is by fuel oil static pressure, exhaust valve is closed, and guarantees the performance of oppositely sealing.Motor 2, impeller, snail chamber, pump oil-in 4 check valve all do not change.
Claims (2)
1. a fuel tanker exempts from quick change fuel pump of draining the oil, comprise pump outer cover, impeller, snail chamber and Outlet check valves, it is characterized in that: on the oil circuit between the snail chamber and Outlet check valves of pump, be provided with exhaust valve, the valve lid of described exhaust valve is made by elastomeric material.
2. a kind of fuel tanker as claimed in claim 1 exempts from quick change fuel pump of draining the oil, and it is characterized in that: described valve lid is made up of elastomeric material.
