## Abstract

A condensate drain for pressurized gas systems, having a condensate collecting chamber, which can be connected to the pressurized gas system via a condensate inflow and has a condensate outflow that can be closed by means of an operable valve, at least one electronic filling level gauge, with which the condensate filling level in the condensate collecting chamber can be detected, and an electronic control unit, with which the condensate filling level detected by means of the filling level gauge can be evaluated and the valve can be operated, where the condensate drain has at least one battery, which provides the power supply for at least the control unit, the filling level gauge and the valve.

## Claims

### Claim 1

A condensate drain for pressurized gas systems, comprising:
a condensate collecting chamber, which can be connected to the pressurized gas system via a condensate inflow and has a condensate outflow that can be closed by means of an electrically operable valve,
at least one electronic filling level gauge, with which the condensate filling level in the condensate collecting chamber can be detected,
an electronic control unit, with which the condensate filling level detected by means of the filling level gauge can be evaluated and the valve can be operated, and
at least one battery, which provides the power supply for at least the control unit, the filling level gauge and the valve.

### Claim 2 (depends on 1)

The condensate drain according to claim 1,
wherein
the battery is a rechargeable battery and at least one power generator is provided, with which electrical energy can be generated from a flow of fluid and which is fluidically connected to the valve downstream thereof and provides the generated electrical energy to the battery in order to charge the battery.

### Claim 3 (depends on 1)

The condensate drain according to claim 1,
wherein
the battery is a rechargeable battery, and a pressurized gas outlet is provided on the condensate drain to let out pressurized gas from the pressurized gas system, and at least one power generator is provided, with which electrical energy can be generated from a flow of fluid and which is fluidically connected to a second electrically operable valve downstream of said valve, with which the pressurized gas outlet can be closed, and which provides the generated electrical energy to the battery in order to charge the battery.

### Claim 4 (depends on 3)

The condensate drain according to claim 3,
wherein
the pressurized gas outlet is arranged on the condensate collecting chamber above a maximum condensate filling level.

### Claim 5 (depends on 1)

The condensate drain according to claim 1,
wherein
the power generator is a power generator functioning in accordance with the piezoelectric principle and having a piezo crystal that is activatable by pressure swing loads caused by the flow of fluid, or is a power generator functioning in accordance with the dynamo principle and having a turbine wheel that can be driven by the flow of fluid.

### Claim 6 (depends on 1)

The condensate drain according to claim 1,
further comprising a radio module, with which alarm signals and/or the operating state of the condensate drain can be transmitted to an attendant and/or a telephone of a maintenance worker.
