Patent ID: 7942034

Claim:
A pressure air regulator comprising: a receive unit comprising an inlet aperture and a first contact surface, the first contact surface comprising at least one exit aperture connected to the inlet aperture; a distribution unit rotatably pivoted relative to the receive unit, the distribution unit comprising a second contact surface, the second contact surface contacting the first contact surface and comprising at least two entrance apertures located at a rotational trajectory of the at least one exit aperture, the distribution unit further comprising at least two distribution apertures, each connected to an entrance aperture, thus providing pressure air when the entrance aperture overlaps with the exit aperture; and a rotating means for generating a relative rotation of the receive unit and the distribution unit, the pressure air regulator configured to test a mechanical input device of a wireless telecommunication device, the distribution unit comprising a radially symmetric chamber, the receive unit comprising a radially symmetric disk-like structure fitted into the radially symmetric chamber and being rotationally conjugated with the distribution unit by an axis.
