Description

The invention relates to filling stations and can be used in the filling of highly flammable liquids from tanks of machines having internal combustion engines.

A device for charging machines is known, comprising a housing with a fluid channel, a drain connection connected to it, a fluid valve and a control unit for its operation, including a pusher with a lock located in the housing.

A disadvantage of this device is the limited functionality for deviating the drain pipe from the vertical or foaming the fuel, as well as low reliability due to the use of a spring and the possibility of steam-air mixture leaking between the cup and the drain pipe.

The purpose of the invention is to increase the reliability of the device in operation and simplify the design.

The goal is achieved by the fact that the control unit is equipped with a cylinder with a mesh bottom rigidly fixed on the drain pipe and a float located in it, while at the open end of the cylinder a different-arm lever is pivotally fixed, the larger arm of which is pivotally connected to the float and the smaller one with the plunger, In the upper part of the latter, inside the case, a spring is installed.

The valve control unit is made in the form of a float, freely placed in a cylinder, the bottom plate of which is made in the form of a grid. This is necessary in order to ensure that the float moves as it floats up in the fuel under the action of buoyancy force to ensure that the pusher descends with a lock and releases the shaped cam with the groove. This stops the supply of fuel, as the supply valve closes. The mesh is necessary to prevent the float from lowering below the slice of the cylinder in order to avoid a thin aluminum case.

The cylinder is rigidly fixed on the drain pipe. This ensures a fixed position of the float and its movement in a strictly defined direction, even if the axis of the discharge nozzle deviates from the vertical.

Figure 1 shows the proposed device; FIG. 2 is a view A of FIG. 1;

The device comprises a housing 1 with a fluid channel, a drain branch pipe 2 connected to it, an activation lever 3 located on axis 4 and having a profiled cam 5 with a groove, a fluid supply valve 6, a pusher 7 with a lock 8 for controlling valve operation.

Valve 6 is pivotally connected to the switching lever and held in the closed position.

position spring 12.

The float 9 is located in the cylinder 13 with the mesh bottom 14 and is pivotally connected by the racquet 7 with the lever 10. The axis of the lever is fixed on the wall of the cylinder

13, with the smaller lever arm 10 being connected to the pusher 7. In the upper part of the pusher 7 there is a spring 11 acting on the body 1 and the upper part of the pusher 7. The device operates as follows.

Fuel under pressure enters the housing 1 and passes through its channels to the valve 6 of the fluid supply.

When you press the lever 3 inclusion profiled Cam 5 with a groove rotates around the axis 4. Spring 11 provides the lifting of the pusher 7 and pushes the latch 8 into the groove. The valve 6 opens, and the latch 8 holds the lever 3 is turned on

position corresponding to the open valve. There is a fuel supply to the fuel tank.

When the fuel level rises to the cylinder 13, the float 9 starts to float, through the 10-arm lever 10 t there is no pusher 7, compressing the spring 11 and releasing the retainer 8, which comes out of the groove of the profiled cam 5. The spring 12 closes the flow valve 6, blocking the flow of liquid.

Application of the proposed device

ensures that the flow is blocked at different angles of inclination of the drain pipe 2. In addition, the float floats even on the foamed product, which significantly expands the range of liquid supply, and the use of a double-arm lever allows to significantly increase the sensitivity of the device.

. The design of the automatic closing mechanism is substantially simplified.
