Abstract

The present invention relates to an automatic mission oil changer of an automobile, and in particular, can prevent new oil from being contaminated by manger, can significantly reduce the production cost of the product, the usability of the oil changer and the efficiency of oil change operation. In addition, it is possible to greatly improve the number of new oil tanks, so that it is possible to accurately supply the specified oil according to the model.

To this end, the suction coupler 2 and the first valve 3 are installed at one end, and the glass tube 4 is installed at the middle part, and the other end thereof is connected to the first pipe 5 connected to one inlet of the three-way valve 10. and; A second pipe (8) having one end with a pressure gauge (6) installed at the outside for circulating the mission oil and a first one-way valve (7) installed at the other end to prevent back flow of oil; Trough induction pipe having a coupler 91, one end of which is selectively coupled to the first nipple 221 installed in the trough tank 22, at the other end fixed to another inlet of the three-way valve 10 ( 9); A three-way valve 10 for guiding oil in the automatic mission by selecting one of the trough tank 22, the waste trough 13, or the first oil filter 21; One end is fixed to the outlet side of the first oil filter 21 and the other end is an inlet coupler (11) that can be selectively coupled to the inlet of the automatic mission (1) or the nipple (231) installed in the new oil tanks (23) A third pipe 12 installed with; One end is provided with a coupler 14 for connecting to the waste stream 13, and the middle part is provided with a second one-way valve 17 installed in the state in which the second valve 15 is installed through the fifth pipe 18. A fourth pipe 16 connected to the other inlet of the first oil filter 21 and connected to one side of the pump 20; A pressure switch 19 for controlling the driving of the pump 20 by sensing the pressure when fresh oil is supplied; A first oil filter 21 for filtering debris contained in new oil and trough; Trough tank 22 for collecting the waste oil in the automatic mission (1); In order to automatically receive fresh oil from the outside, each of the sieves having nipples 231 selectively coupled with the inlet coupler 11 of the third pipe 12 and connected to the inlet side of the multidirectional valve 28, respectively. Several new oil tanks 23 each containing oil designated for each vehicle type; A sixth pipe 27 provided with a second oil filter 24, a third valve 25, and a glass tube 26; A multi-directional valve 28 which selects one of the several new oil tanks 23 and connects it to the sixth pipe 27; In the state where the coupler 311 for connecting to the new oil supply cylinder 29 or the second nipple 222 of the trough 22 and the fourth valve 30 for controlling the opening and closing of the pipe are installed at one end. The end is constituted by the seventh pipe 31 connected to the middle portion of the sixth pipe 27.
