LIQUEFIED GAS FILLING DEVICE

The utility model relates to means of supplying fuel, namely gas, and can be used at automobile gas stations when refueling vehicles operating on liquefied petroleum gas (propane-butane).

As a result of a patent search, fueling devices for supplying liquid fuel were found.

A device for dispensing a fluid supply according to copyright certificate No. 1541183, according to class. B 67 D 5/12, publ. 02/07/90, in which there are nozzles, springs, a rod, a membrane, a check valve, a dosing regulator and a handle.

The closest technical solution to the claimed utility model is a dispensing gun according to the patent of the Russian Federation No. 2147534, according to class In 60S 5/02, publ. 04/20/2000, in which there is a housing, a lever, nozzles, a rod for turning on a crane-gun.

However, the known analogues are intended only for supplying liquid fuel and have a rather complex and time-consuming design.

The technical task of the utility model proposed for patenting is the creation of a refueling device of a design that is simple and reliable in operation.

The technical problem is solved by the fact that the filling device, including; its body, handle (lever), rod, main spring and gas input device (features similar to the closest analogue), is equipped with new design features: a spool installed inside the additional housing under the rod, moreover, side holes are made on the sides of the spool, and on the side surface of the valve body from the gas inlet side there is one hole for installing a gas inlet device in it, which is made in the form of a pipe, rigidly connected to the valve body and having its hole, the diameter of which is equal to the diameter of the side hole on the valve body and the side holes of the valve, while the holes on the valve, the holes on the valve body and the nozzle holes, when combined, form a through hole for gas inlet.

An additional squeezing lower spring is installed in the lower part of the valve body, several o-rings are installed on the outside of the valve in its grooves. The housing of the refueling device in the lower part is made in the form of a special gripper of a staple shape. The handle on the housing of the refueling device is equipped with an eccentric, which is located with its protrusion

horizontally the end face of the Rod having a guide connected to the boss, which is rigidly fixed to the housing of the filling device.

The drawing shows a refueling device in a general view.

The device consists of a housing 1, in the upper part of which a handle (lever) 3 with an eccentric 4 is mounted on the hinge 2, which protrudes horizontally at the end of the rod 5, having a guide 6, which is connected to the boss 7 to hold the rod in the housing 1, which in turn, it is rigidly fixed (with screws) to the housing 1, on the side surface of which, from the gas inlet side, a slot 8 is made for free movement of the gas inlet device, inside the housing 1, under the stem 5, an additional housing 9 is installed, in the inside of which th set spool 10c side holes 11. On the side surface of the casing 9 on the input side gas formed a lateral opening 12 for mounting therein a device for introducing gas formed in the form of a pipe 13 rigidly connected with the housing of the spool 9. The gas inlet has a hole 14, the diameter of which is equal to the diameter of the side hole 12 on the valve body 9 and the side holes 11 of the valve. Holes 11, 12 and 14, when combined, form one through hole for gas inlet.

An upper spring 15 is installed in the upper part of the spool, and an additional lower squeezing spring 16 is installed in the lower part of the valve body 9 of the spool 16. On the outside of the spool, in its grooves, several rubber o-rings 17 are installed.

The housing 1 in its lower part is made in the form of a special gripper in the form of a bracket for installing and securing the filling device on the fitting 18 of the vehicle tank 19.

The filling device operates as follows.

For refueling, for example, a car, the refueling device with the lower grips of the housing 1 is mounted on the fitting 18 of the tank 19, pressed to it by pressing down to the stop of the handle (lever) 3 with an eccentric 4, which shifts the axis of the handle relative to the axis of the moving rod 5, while the rod 5 along the guide 6 presses on the housing 9 of the spool 10 and compresses the squeezing lower spring 16, and the spool 10, in this case, falls down together with the housing 9, under the action of the upper spring 15 being compressed by the housing until it stops in the fitting 18. At the same time, the spool 10 is lifted into it core pus 9, and the upper spring 15 is reduced. There is a combination of the side holes 11 of the spool with the side hole 12 on the body of the spool and the hole 14 in the nozzle, and the resulting through hole through the nozzle 13 begins to flow

.. under pressure liquefied gas, which through the spool 10 and the fitting 18 enters the tank 19 of the car.

To stop the gas supply to the car tank and remove the refueling device from the fitting 18, it is necessary to lift the handle (lever) 3 up. In this case, the rod 5 is released, and the lower squeezing spring 16 unclenches, raises the valve body 9 together with the spool 10 and the rod 5, and releases the filling device from the nozzle 18. At the same time, the upper spring 15 opens and lowers the valve 10 in the housing 9. The hole is displaced 11 of the spool relative to the hole 12 on the spool housing and, the gas supply to the vehicle tank is shut off.

The gas supply is cut off earlier than the spool is disconnected from the filling nozzle due to the small stroke of the spool and the quick closing of the holes, which prevents gas emission into the atmosphere. The filling device closed for gas passage is removed from the fitting.

The proposed filling device in comparison with known similar devices has the following advantages:

1. Simplicity and reliability of the design. Only rubber o-rings, which change easily, come into wear.

2. In the manufacture of a filling device, its metal consumption is significantly reduced.

3. The use of a slide valve with a smooth overlap of the passage of liquefied gas does not cause water hammer and gas emission into the atmosphere when closing and opening the gas passage and when removing the filling device from the car tank fitting (as happens in known similar devices).

4. In the proposed design of the filling device, there is no sealing lip, and therefore, any solid particles pass into the vehicle’s tank, which ensures high performance characteristics of the proposed utility model.
