Description

ARSAG Albert, Saint-Pierre-Duchamp (Haute-Loire), France

Device for filling or draining water into or out of mainly agricultural tractors or high-strength tires used in public works.

The present invention mainly relates to a device for filling or discharging water into or from Tires used in agricultural tractors or in public works.

Devices are known which are designed to effect these processes, but their implementation is complicated result in a high cost price, which in particular its spread in less important garages is detrimental.

The device according to the invention allows this disadvantage to be overcome. For them is the cost price little due to their simplified implementation possibilities high.

According to a first characteristic feature, this device a slektropump set to which on the one hand a submerged in a water reservoir such as a basin or a pool Feed line is connected while the other hand Distribution lines provided with shut-off valves are connected, at the jinden of which there is a coupling device: is provided, which can be connected to one or the other of the tractor wheels to their bows accordingly to fill with water.

Appropriate allowance according to another characteristic feature independently provided plug-in valves, which are connected to a line provided with a shut-off valve for discharging the v / ösaerc from the iioifen are connectable, these lines occasionally its repair or its replacement p; e; -; en to be able to empty another.

These and other characteristic features will also emerge from the following description.

The drawings show the subject matter of the invention without wishing to restrict it by them.

Figure 1 is a small-scale schematic View of the device according to the invention the occasional filling of water into one Tires. The arrows indicate the direction in which the water is running and the direction in which the tire is filled outgoing air.

Fig. 2 is also kept on a small scale schematic view of the device according to the invention in the event of a tire being deflated. The arrows show the path of compressed air flowing into the interior in the event of evacuation of the water.

The device according to the invention, which is used for filling a tractor tire with water or emptying it by draining it of the water from this is used, has an electric pump set 1 constructed in a known manner, on whose Inlet nozzle 1 is connected to a line 2, which at its opposite end in a trough or a Cystern 3 is immersed and over a filter or suction head with here arranged check valve 4- leads.

The outlet nozzle 1, from which the pressurized water of the electric pump set 1, has a plug 5 with two outlets for the connection of two distribution lines 6 and 7, each of which to the corresponding connection to a Tire is intended.

Each distribution pipe 6 or 7 is equipped with a shut-off valve 8 or 9 provided, to which the water flow is subordinate, and on the other hand with its free end with an attachment or Aufsetz- piece 10 equipped, which can be fastened by screwing onto the connecting part 11 of the tire. An independent one

Roiirteil 12 also passes through the axial opening of the Attachment or Aufsetzstückes 10, in order to be in the interior of the Keifens P

1 to open out, forming an annular gap 10, which is used to give the water a free To allow passage.

With a system constructed in this way, this is the case when it is initially closed Taps 8 and 9 of the electric pump set 1, if necessary, by being drawn from a container Pour water into the pipes 2, 6 and 7, make it ready for operation, then the taps 8 and 9 »d © after, whether one or two tires are to be filled, opened. The electric pump set then makes it possible for his company to to introduce water under pressure into any tire, this through the annular gap 10 of the connection part 10 flows in, while the air flows through the pipe part 12 in accordance with the increasing water filling of the tire is progressively expelled outward through the tube 12.

According to ELg.2, the maturity is emptied according to the invention by means of a discharge line 13 equipped with a tap 14 · This line instructs one end of a connector 15, which on the Connection body 11 is attached by screwing on the opposite outer end of which is fixed by welding or otherwise * ie a valve 16 of known type, which is intended to be able to blow compressed air into the interior of the tire.

At the opposite end of the pipe 1 $ this is immersed in a trough for the purpose of reusing the water a.

When the tire is emptied by draining the water, the tap 14 is initially closed and passes through the valve 16 and the connection part 15 compressed air into the interior of the tire to there an overpressure of to bring about sufficient height.

When the tap 14 is opened, there is then a pressure gradient which, via the drain line 13, leads to complete emptying of the tire by draining the water into the trough 3.

The device according to the invention can be implemented in a simple manner and is easy to handle. She shows herself in particular useful and valuable even for less important garages.

The invention is by no means in the described manner and way of applying it, nor is it the illustration of the Forms of realization of its various parts were limited, which were shown more in particular. 3ie encloses in this respect, rather, all conceivable modifications at the same time.
