Abstract
The invention discloses an automatic automotive diesel engine fuel pipe intake air exhaust mechanism, which comprises a pushing force generator, an exhaust switch, a contactor, a fuel-recovering pipe, a relay and an electromagnetic valve. The pushing force generator is used for generating pushing force; after the air enters an automotive diesel engine fuel pipe, when a manual fuel pump needs to be pressed to exhaust the air, the relay can close according to a certain cycle as long as the exhaust switch is pressed, as a result, by controlling the contactor, the pushing force generator can automatically press the manual fuel pump according to a certain cycle until the air is completely exhausted, and consequently, the labor difficulty and intensity of an operator in manual exhaust is eliminated; since the electromagnetic valve is used for substituting for the conventional bleed screw of the diesel engine fuel pipe, during exhaust, not only can the air be effectively exhausted, but also fuel can be conveniently recovered by the fuel-recovering pipe mounted on the electromagnetic valve, and thereby waste and pollution are prevented.
Description
Technical field
The present invention relates to after the air inlet of a kind of diesel engine for automobile fuel pipe emptying mechanism automatically.
Background technique
Because after the air inlet of diesel engine for automobile fuel pipe, diesel engine can't start, vehicle also just can't go, the air in the therefore necessary emptying fuel pipe, and diesel engine for automobile is provided with hand fuel pump specially for this reason.Though the hand fuel pump of the diesel engine of producing now all is just directly to push to carry out emptying; But, when the needs emptying, the necessary manually-operable of operator; Cab tilt at first also; Perhaps move seat etc., if the operator lacks experience, this process will repeat repeatedly could start vehicle; Moreover operator also will open bleeder screw before pushing hand fuel pump, and when pushing hand fuel pump to a certain degree the time, fuel oil will be from bleeder screw along with air is together directly discharged.
Obviously, carry out the air that gets in the emptying diesel engine fuel oil pipe, have and do not attain perfect disappearance with hand fuel pump:
(1) operator must open bleeder screw, cab tilt or mobile seat etc., just can push hand fuel pump, and this has just increased labor intensity and difficulty.
(2) in the process of manually emptying, fuel oil causes waste and pollution along with air is directly discharged outside the car.
Summary of the invention
For overcoming the deficiency of existing technology; The technical problem that the present invention will solve provides after the air inlet of a kind of diesel engine for automobile fuel pipe emptying mechanism automatically; When diesel engine because during the emptying of fuel pipe intake requirement; Operator only need press air discharge cook just can will get into the air emptying in the fuel pipe, has not only eliminated operator's labor intensity and difficulty, but also has avoided waste and pollution.
For addressing the above problem, the technological scheme that the present invention adopts is:
The thrust generation device be by: sealed cap, housing, starting coil, push away body, stroke coil, interior cover, spool, stiff spring, support, air drain, position limit switch, by the formation of presenting a theatrical performance as the last item on a programme, be used for producing the thrust of vehicle hand fuel pump;
The emptying switch is used for connecting after the air inlet of diesel engine for automobile fuel pipe the power supply of emptying mechanism automatically;
Contactor is used for controlling the power supply of thrust generation device;
Collection tube is used for reclaiming the fuel oil of together discharging with air;
Relay, relay coil be by stable multi-oscillation circuit control, is used for pickup time of control contactor;
Solenoid valve is installed in the position of the original bleeder screw of diesel engine for automobile fuel pipe, during emptying, is used for emitting the air in the fuel pipe.
The invention has the beneficial effects as follows: emptying mechanism automatically is provided after the air inlet of a kind of diesel engine for automobile fuel pipe, and this mechanism has adopted the thrust generation device, produces the needed thrust of hand fuel pump oil transportation; After the air inlet of diesel engine for automobile fuel pipe; Operator only need press air discharge cook: on the one hand, the thrust generation device is by the automatic reciprocating hand fuel pump oil transportation of pushing diesel engine for automobile of certain cycle, on the other hand; Solenoid valve is opened; Deflate, the fuel oil that will discharge along with air simultaneously reclaims through collection tube; This shows that operator's labor intensity, difficulty not only eliminated by this mechanism, also reclaimed fuel oil, avoided waste, pollution.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
Accompanying drawing 1 is the schematic representation of thrust generation device of the present invention.
Accompanying drawing 2 is the stable multi-oscillation circuit theory diagrams.
Embodiment
With reference to accompanying drawing 1; The thrust generation device be by: sealed cap (1), housing (2), starting coil (3), push away body (4), stroke coil (5), interior cover (6), spool (7), stiff spring (8), support (9), air drain (10), position limit switch (11), constitute, be used for producing the thrust of vehicle hand fuel pump by present a theatrical performance as the last item on a programme (12); The position of adjustment thrust generation device and hand fuel pump makes to push away body (4) and hand fuel pump corresponding contact, after starting coil (3) energising; Under the effect of the electromagnetic force that spool (7) will be produced in starting coil (3), begin to move downward, behind the certain stroke of spool (7) motion; Make position limit switch (11) action that is fixed on the support (9) by present a theatrical performance as the last item on a programme (12), thereby connect the power supply of stroke coil (5), the power supply of cut-out starting coil (3), because starting coil (3) and stroke coil (5) have structurally adopted certain position relation; Not only spool (7) can not retreated because of the dead electricity of starting coil (3), and spool (7) continues to move downward under the electromagnetic force effect that stroke coil (5) is produced on the contrary; Be connected pushing away body (4) and will push hand fuel pump below the spool (7), after stroke coil (5) dead electricity, so with push away the spool (7) that body (4) is connected will be under the reaction force of hand fuel pump; Keep in the center; Realize once coming and going of hand fuel pump, this process was carried out according to certain cycle, just the interior air of emptying fuel pipe automatically; Stiff spring (8) plays damping function at spool (7) when keeping in the center; Air drain (10) is in the reciprocating process of spool (7), and cover (6) air in the conducting, interior cover (6) be spool (7), push away the reciprocal passage of body (4);
The emptying switch is used for connecting after the air inlet of diesel engine for automobile fuel pipe the power supply of emptying mechanism automatically;
Contactor, according to the cycle that relay provides, the conducting or the disconnection of control thrust generation device power supply;
Collection tube is installed on the solenoid valve, is used for reclaiming the fuel oil of together discharging with air;
