Patent ID: 8631823

Claim:
A mixing faucet for two liquids at different temperatures, the mixing faucet comprising: a mixing valve, a perforated plate valve having at least one actuation quantity that alone determines a volume of an outflow of the two liquids; a first rotary actuator mounted in a fixed housing so as to be rotatable in one rotational degree of freedom relative to the fixed housing, wherein a rotation of the first rotary actuator provides adjustment of at least one of two independent coaxial rotational control variables for controlling volume or temperature of the outflow, wherein the at least one of the two rotational control variables is selectable by two fingertips placeable on approximately opposite sides of an outer envelope surface of the first rotary actuator and wherein the at least one of the two rotational control variables is selectively adjustable by one hand that remains in a permanent position in the direction of access over the entire range of adjustment, a first planar multi-link conversion gear that comprises conversion gear elements and conversion gear links, wherein the conversion gear links each connect two of the conversion gear elements to each other with at least one degree of freedom; wherein the first planar multi-link conversion gear is of substantially rotational symmetry relative to a drive axis thereof, wherein the drive axis is an axis of rotation of the one of the two rotational control variables; wherein the first rotary actuator is operatively connected to the first planar multi-link conversion gear and the conversion gear elements all move relative to each other when the first planar multi-link conversion gear is acted on by the first rotary actuator; wherein, when the first rotary actuator is adjusted, the first planar multi-link conversion gear converts the at least one of the two rotational control variables to the at least one actuation quantity on a plane that is parallel to a slip plane of the perforated plate valve.
