Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is into Fig. 5, a kind of screw air compressor fueling injection equipment, including positive screw rod 8, further includes Fuel Injector Bar 1 and oil pipe 2, spray
1 both ends of beam hanger are extended with shaft 6, and shaft 6 is connect with extraneous power device, so that Fuel Injector Bar 1 is with suitable rotational speed.
Oil pipe 2 is connected with extraneous oil liquid, and the spiral groove 3 being meshed with positive screw rod 8 is offered on 1 outer wall of Fuel Injector Bar,
Several gear oil clots 4 and through-hole compatible with gear oil clot 4 are provided in spiral groove 3, gear oil clot 4 can be in through-hole freely
Sliding, gear oil clot 4 are also connected with the reset spring 7 of consistent reach through hole, and gear oil clot 4 is also connected with oil injection plate 5, oil injection plate 5 and gear
Oil clot 4 is bonded and opposite can slide, and is additionally provided with several jets on oil injection plate 5.There are two oil injection plates 5 and is oppositely arranged, and keeps off
Oil clot 4 is set between two oil injection plates 5, and two oil injection plates 5 can play the role of fixed gear oil clot 4, avoid gear oil clot 4 because
To be mobile oil liquid is revealed.
Jet is evenly distributed on oil injection plate 5 and the area of oil injection plate 5 is no more than oil injection plate 5 and gear 4 contact position of oil clot
Area effectively can avoid oil liquid from revealing.
Highly preferred embodiment of the present invention the most, gear oil clot 4 be elastomer block, can be effectively prevented oil liquid leakage, oil injection plate 5 with
