APPARATUS DISTINGUISHING BETWEEN GASOLINE AND DIESEL OIL IN FUEL-OIL DISPENSERS

Abstract

A filling apparatus for filling gasoline and diesel vehicles at fuel oil stations and installed onto a fuel oil dispenser having a cap located on dispenser pipe entering into the vehicle tank. A diaphragm is located in the cap and operates the fuel oil way and provides flow and stop of fuel oil. A pipe sheath is installed onto the dispenser pipe and connected to the cap. A holding spring secures the pipe sheath to body of the fuel oil dispenser. A trust pipe provides a set of trust mechanism resting on the tank inlet when it is attempted to insert pipe sheath into the diesel tank. A pushing spring is connected to the thrust pipe and pushed after the tank inlet is hit by the thrust pipe. A motion spindle transmits motion from the pushing spring to the diaphragm which is moved downward and provides closing.

DETAILED DESCRIPTION OF THE INVENTION

Embodiment Principle

[0025] Filling apparatus (100) in general consists of a cap (110), a spindle (120), a set lever 1 (130), sheet 2 (140) and a pipe sheath (150). FIG. 1 shows perspective view of filling apparatus (100).

[0026] Said cap (110) spindle (120) and lever arm (121) provide opening-closing of diaphragm (160). Cap (110) is placed on fuel oil dispenser (10) and is connected to dispenser pipe (11) through which liquid flows. The cap (110) is fixed onto fuel-oil dispenser (10) by fixing members (111).

[0027] Diaphragm (160) is the member moving up and down on the cap (110) and thus opening and closing the dispenser pipe (11). Lower part of diaphragm (160) has a diaphragm spindle (161). Diaphragm spindle (161) is the component pushing assembly downward in order to prevent flow of fuel into dispenser pipe (11). General structure of diaphragm (160) is flexible surface (162). Centre of flexible surface (162) contains spindle connection part (163) providing fixing of diaphragm spindle (161) to flexible surface. In addition, edges of flexible surface (162) have diaphragm fixing holes (164) used for fixing the diaphragm (160) into cap (110), FIG. 5 is a perspective view of the diaphragm (160).

[0028] Diaphragm cover (112) is located in upper part of diaphragm (160) and thus diaphragm (160) is trapped into the cap (110).

[0029] Motion spindle (120) is placed in the cap (110) horizontally. It plays active role in opening-closing actions of diaphragm (112). Lever arm (121) is located on motion spindle (120). Lever arm (121) is fixed onto motion spindle (120) by means of fixing member (122). Said lever arm (121) contacts flexible surface (162) of diaphragm (160) and moves diaphragm spindle (161) up and down. FIG. 3 is a perspective view of the motion spindle (120).

[0030] Set arm 1 (130) and sheet 2 (140) are interconnected by set arm fixing member (131) and provide interconnection of pipe sheath (150) and cap (110). It rotates and acts as joint where fixed to each other.

[0031] Set lever 1 (130) is fixed to motion spindle (120) inside the cap (110).

[0032] Sheet 2 (140) is fixed to set lever 1 (130) on one side and to pipe sheath (150) on the other side. The fixing operations are conducted by use of set lever fixing members (131). Gasket (132) is used to prevent loosing in set lever fixing members (131).

[0033] Pipe sheath (150) is the embodiment put onto dispenser pipe (11) and sliding onto the dispenser pipe (11) to move. Holding spring (151) consists of nipple (152), spring holder (153), pushing spring (154), trust pipe (155). FIGS. 1 and 2 show pipe sheath (150) and cap (110) embodiment clearly.

[0034] Holding spring (151) is a connection part used for centring. It provides connecting terminal part of pipe (11) of dispenser to upper part and provides connection of pipe sheath (150) to dispenser pipe (11).

[0035] Nipple (152) is the part providing installation of system wherein set lever arm 2 (140) is fixed to pipe sheath (150).

[0036] Spring holder (153) is the connection part providing connection of pushing spring (154) to the system.

[0037] Pushing spring (154) is the component inserted to trust pipe (155) and transmitting the motion from trust pipe (155) to set lever 2 (140).

[0038] Trust pipe (155) is the connection part providing activation of system by contacting fuel oil tank.

Principle of Mounting

[0039] The cap (110) and pipe sheath (150) constituting filling apparatus (100) are interconnected by set lever 1 (130) and set lever 2 (140). The filling apparatus (100) with this connection is shown in FIG. 1.

[0040] Thereafter, firstly pipe sheath (150) is put onto the dispenser pipe (11) to fix onto the fuel oil dispenser (10). The cap (110) is located onto fuel oil dispenser (10).

[0041] The diaphragm (160) is located inside the cap (110). The motion spindle (120) to be connected to diaphragm (160) is fixed inside the cap (110) by means of fixing member (122). During fixing, the motion spindle (120) is connected to set levers 1 (130) from side edges and thus connected to the system.

[0042] This section is closed after location of the diaphragm cover (112) onto the cap (110). Diaphragm cover (112) is fixed onto the cap (110) by means of fixing members (111). The fixing members (111) also pass through diaphragm fixing holes (164) and fixing of diaphragm (160) into the cap (110) is provided.

[0043] It is in the form shown in FIG. 4 after this fixing. Trust pipe (155) located in the pipe sheath (150) may slide in direction B subject to pressure from outside, and when left free, restore to former position after sliding in direction A.

Principle; of Operation

[0044] When gasoline is filled, trust pipe (155) grasping the dispenser pipe (11) rests on edges without entering tank hole while fuel oil dispenser (10) is inserted in vehicle tank. Meanwhile, when dispenser pipe (11) is pushed inward, the trust pipe moves in direction B. The trust pipe (155) moving in direction B also pushes the pushing spring (154) connected to it. Similarly, spring holder (153) and nipple (152) fixed to pushing spring (154) move in direction B.

[0045] Upon motion of all the members, set lever 2 (140) move in direction B. With this motion, set lever 1 (130) moves in direction B from the point where it is connected to set lever 2 (140) and the section fixed to the cap (110) starts to rotate around its axis.

[0046] Since set lever 1 (130) is fixed to motion spindle (120) inside the cap (110), the motion spindle (120) also rotates around its axis upon final motion of sheet 1. Rotation of motion spindle (120) around its axis moves the lever arm (121) downward. The lever arm (121) moving downward contacts the flexible surface (162) of the diaphragm (160) and lowers the flexible surface (162) in down direction. Flexible surface (162) moving downward moves the diaphragm spindle (161) connected to it and closes the inlet of dispenser pipe (11) and stops fuel oil flowing.

[0047] The invention is used to prevent pour of gasoline to diesel vehicles. The inlet section of fuel oil tank of diesel vehicle is narrower than inlet of tank of gasoline vehicle.

[0048] Filling apparatus (100) is installed onto the fuel oil dispensers (10) filing gasoline as described above. When petrol station officer attempts to put the fuel oil dispenser (10) into diesel vehicle tank by mistake, trust pipe (155) coincides with narrow diameter tank inlet and as stated, the mechanism is set and the diaphragm (160) closes the dispenser pipe (11) way. Thus pour of gasoline into diesel engine tank is prevented.

[0049] As stated above, since diameter of inlet part of fuel oil tank of gasoline vehicle is wider, it takes the dispenser pipe (11) having filling apparatus (100) installed thereon and provides progress of filling.
