Abstract
An espresso machine provided with a rotating ceramic disk valve (1) as a selective water-steam distributor that is in a driving connection with a drive motor (2), and a control device (3) for controlling the drive motor (2). To increase the precision of the rotational-angle setting, a Geneva gear (4) is incorporated into the driving connection between the drive motor (2) and the rotating ceramic disk valve (1), with the gear setting the rotating ceramic disk valve (1) in make-and-break cycles. The control device (3) shuts off the drive motor (2) after at least one make-and-break cycle of the Geneva gear (4).
Claims5
In an espresso machine having a rotating ceramic disk valve as a selective water-steam distributor, a driving connection a drive motor connected to the valve via a driving connection to rotate to the valve to desired angular positioning and a control device for controlling the drive motor, the improvement comprising:
- Geneva gear incorporated into the driving connection between the drive motor and the rotating ceramic disk valve, with the gear setting the position of the rotating ceramic disk valve in make-and-break cycles, and the control device incluidng means for switching off the drive motor after at least one make-and-break cycle of the Geneva gear.
