Abstract
The device for inflating pneumatic tires comprises an inlet of pressurized air and an outlet for sending the air into a pneumatic tire. A first circuit of the device is divided into an initial tract and a final tract, which connects the inlet with the outlet, passing through a first on-off valve provided with a membrane. A second circuit of the device connects the inlet with a first chamber of the first on-off valve. The first chamber is also connected to a pressure regulator connected at outlet to a second on-off valve, which intercepts the air flow. A third circuit connects the outlet to a first chamber of the second on-off valve.
Claims6
A device for inflating pneumatic tires, comprising:
- an inlet of pressurized air and an outlet for sending said air to a pneumatic tire to be inflated;
- a first circuit comprising a initial tract of pipe connecting said inlet to a pressure-sensitive first on-off valve, and a final tract of pipe connecting said first on-off valve to said outlet;
- a second circuit originating at said inlet and connecting said inlet to a first chamber of said first on-off valve;
- said first chamber being separated from a second chamber of said first on-off valve, which second chamber is in direct communication with the inlet, by means of a membrane;
- said membrane being associated to an obturator for intercepting an air flow in outlet coming from said second chamber;
- said first chamber also being connected to a pressure regulator connected at an outlet thereof to a second on-off valve for intercepting air flow;
- a third circuit connecting said outlet to a first chamber of said second on-off valve;
- said first chamber of said second on-off valve being separated from a second chamber of said second on-off valve by means of a membrane;
- said membrane being associated to an obturator for intercepting an air flow in inlet to said second chamber of said second on-off valve, said air flow in inlet coming from the outlet of said pressure regulator.
