Description
FLUID INJECTOR
2 The present invention relates to a fluid injector.
2 The present invention relates to a fluid injector.
3 A conventional fluid injector is shown in Fig. 5, 4 however, there still remain shortcomings therein. There will be a complete illustration in the detailed description 6 of the preferred embodiments, concerning the conventional 7 fluid injector.
8 The present invention has arisen to mitigate and/or g obviate disadvantages of the conventional fluid injector.
In accordance with one aspect of the present invention, 11 there is provided a fluid injector for filling a fluid into 12 a container which has a chamber defined therein and an 13 insertion socket defined in a top portion thereof and 14 communicating with the chamber.
The fluid injector comprises a filling pipe mounted on 16 the container and includes an upper portion located outside 17 of the top portion of the container and a lower portion 18 disposed in the chamber of the container through the 19 insertion socket. A first cavity is defined in a periphery of the upper portion of the filling pipe, and a second 21 cavity is defined in a periphery of the lower portion of the 22 filling pipe.
23 A discharge tube is mounted on the filling pipe and 24 includes a lower portion disposed in the filling pipe and extending through the second cavity, and an upper portion 26 extending outwards of the upper portion of the filling pipe 27 through the first cavity to surroundings. An opening is 28 defined in a distal end of the lower portion of the 21 9~7 1discharge tube and communicates with the chamber.
2Further features of the present invention will become 3apparent from a careful reading of the detailed description 4provided hereinbelow, with appropriate reference to the 5accompanying drawings.
6In the drawings:
7Fig. 1 is a perspective view of a fluid injector in 8accordance with the present invention;
gFig. 2 is a front plan cross-sectional view of Fig. 1;
10Fig. 3 is a front plan cross-sectional view showing the 11fluid injector being assembled with a container and a 12control valve;
13Fig. 4 is a perspective view of a fluid injector in 14accordance with one embodiment of the present invention; and 15Fig. 5 is a front plan partially cross-sectional view 16of a conventional fluid injector in accordance with the 17prior art.
18For a better understanding of the present invention, 19reference is made to Fig. 5 illustrating a conventional 20fluid injector in accordance with the prior art.
21The conventional fluid injector includes a cap 60 22detachably mounted on a top portion 53 of a container 50. A
23filling tube 61 mounted on the cap 60 is engaged on an inlet 24hole 51 defined in the top portion 53 of the container 50 for 25filling fluid such as oil and the like from an oil tank (not 26shown) into the container 50.
27A drainage tube 62 mounted on the cap 60 is engaged on 28an outlet hole 52 de~ined in the top portion 53 of the 21 922~7 1 container 50 for transferring an oil/gas mixture produced 2 during the filling process from the container 50 back into 3 the oil tank. The oil/gas mixture can then be separated into 4 oil and gas and the recovered oil can be conveyed into the oil tank for reuse.
6 By such an arrangement, however, containers 50 of 7 different sizes have top portions 53 of different dimensions 8 such that a span defined between the inlet hole 51 and the g outlet hole 52 is often not identical for containers 50 of different sizes and such that it is necessary to prepare 11 caps 60 of different dimensions so as to suit for containers 12 50 of different sizes, thereby greatly increasing the cost 13 in manufacturing.
14 In addition, the distance between the inlet hole S1 and the outlet hole 52 may not be identical even for a container 16 50 of the same size due to an error in production such that 17 the filling tube 61 and the drainage tube 62 cannot exactly 18 align with the inlet hole 51 and the outlet hole 52 19 respectively, thereby easily causing a difficulty of installation.
21 Referring to the remaining drawings, and initially to 22 Figs. 1-3, a fluid injector in accordance with the present 23 invention is provided for filling a fluid such as oil, 24 petroleum, gasoline and the like into a container 30.
The container has a chamber 302 defined therein, a 26 cylindrical lug 32 formed on and protruding upwardly from a 27 top portion 33 thereof, and an insertion socket 31 defined 28 in the cylindrical lug 32 and communicating with the chamber 21 q226~
1 302.
2 The fluid injector comprises a filling pipe 10 mounted 3 on the container 30 and including an upper portion or upper 4 bent tube 11 located outside of the top portion 33 of the container 30 and a lower portion or lower upright tube 16 6 disposed in the chamber 302 of the container 30 through the 7 insertion socket 31.
8 A first and a second cavity 110 and 160 are defined in g a periphery of the upper and the lower portion 11 of the lo filling pipe 10 respectively.
11 The upper portion 11 of the filling pipe 10 includes an 12 annular flange 13 extending radially and outwardly. A
13 magnetic ring 14 is fixedly mounted on an underside of the 14 flange 13 and abuts on the cylindrical lug 32. The magnetic ring 14 has an outer diameter smaller than that of the 16 annular flange 13 and greater than that of the cylindrical 17 lug 32.
18 A sealing gasket 15 is mounted between the magnetic 19 ring 14 and the cylindrical lug 32 for providing a sealing effect.
21 A discharge tube 20 is mounted on the filling pipe 10 22 and includes a lower portion 21 disposed in the filling pipe 23 10 and extending through the second cavity 160, and an upper 24 portion 22 extending outwards of the upper portion 11 of the filling pipe 10 and through the first cavity 110 to 2 6 surroundings to be engaged in a drainage tube 46.
27 An inlet opening 210 is defined in a distal end of the 28 lower portion 21 of the discharge tube 20 and communicates 2 1 ~ ~2 61 1 with the chamber 210. An outlet opening 220 is defined in a 2 distal end of the upper portion 22 of the discharge tube 20 3 and communicating with the drainage tube 46.
4 In assembly, the upper bent tube 11 of the filling pipe 10 has an inner threaded portion 12 threadedly engaged on an 6 outer threaded portion 41 of a bidirectional connector 40 7 which is coupled with a control valve 42 which is coupled 8 with a first quick connector 43 which is engaged on a second g quick connector 45 of a supply tube 44 connected with an oil reservoir (not shown).
11 In operation, when an operator intends to fill oil into-12 the container 30 from the oil reservoir, the lower tube 16 13 of the filling pipe 10 can be inserted into the chamber 302 14 of the container 30 via the insertion socket 31, with the magnetic ring 14 securely abutting on the cylindrical lug 16 32.
17 The operator can then operate the control valve 42, 18 thereby allowing oil to be injected into the container 30 19 from the oil reservoir via the lower tube 16 and the supply tube 44 until oil in the container 30 reaches a full level-21 or a predetermined position.
22 At the same time, an oil/gas mixture produced in the 23 container 30 during the filling process is transferred 24 through the inlet opening 210 of the discharge tube 20 into the drainage tube 46 via the outlet opening 220 and can then 26 be delivered into the oil reservoir. Finally, the oil/gas 27 mixture can be separated into gas and oil respectively for 28 reuse.
~1 9~267 1 By such an arrangement, the oil/gas mixture can be 2directly returned into the oil reservoir via the discharge 3tube 20, without a possibility of leaking into surroundings.
4In addition, the discharge tube 20 can serve as an 5overflow tube such that when oil in the container 30 exceeds 6a level of the top portion 33, the overflow oil can also be 7directly returned into the oil reservoir via the discharge 8tube 20, thereby preventing the oil from overflowing into gsurroundings.
10Referring to Fig. 4, the upper portion 22 of the 11discharge tube 20 can be disposed in a horizontal manner 12such that the drainage tube 46 connected with the discharge 13tube 20 can by-pass the control valve 42.
14It should be clear to those skilled in the art that 15further embodiments of the present invention may be made 16without departing from the scope and spirit of the present 17invention.
