A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.

A switch assembly for a valve actuator can include a bracket, a rotatable switch rotatably coupled to the bracket at an adjustable angle, a fixed switch fixedly mounted to the bracket, an arm rotatably coupled to the bracket, and an adjustable switch trigger coupled to the arm. The rotatable switch can be tripped by the valve actuator and a trip point of the rotatable switch can be calibrated by setting the adjustable angle. The fixed switch can be tripped by the switch trigger on the arm and a trip point of the fixed switch can be set by adjusting the switch trigger relative to the arm. The assembly can include a calibration fixture for calibrating the switch assembly to the valve actuator independently of the valve actuator.

The present invention provides a smart monocontrol cartridge for taps, a smart tap that incorporates said cartridge, and a smart system that incorporates said tap, the monocontrol cartridge comprising a based with a lower end, an upper end for coupling to ceramic discs and an intermediate portion in which a recess is defined in which an electronic module is coupled that is configured to house indirect temperature detection means configured to detect the temperature in the mixed water channel and electronic means configured to calculate the real temperature in the mixed water channel based on an indirect temperature detection, the indirect temperature detection means being in data communication with the electronic means; and wherein a flexible cable is coupled between the electronic module and the cam.

A device is provided for controlling the ignition of gas burners of a domestic cooking appliance. The device includes an electric switch with an insulating casing that carries a pair of fixed electric contacts. A movable body carries a movable electric contact that cooperates with the fixed electric contacts. The movable body is displaceable with respect to the casing between an open position and a closed position. An elastic element elastically pushes movable body toward the open position. A flexible cable has a first end that is anchored to the movable body and a second end that is anchored to a fixed support. A plurality of actuating members is associated with respective gas taps and have movable elements that cooperate with respective sections of the flexible cable. Each actuating member can bend a respective portion of the flexible cable into corrugated shape during the opening of the respective gas tap.

An air compressor includes a cylinder and a piston reciprocably movable inside the cylinder, an electric motor configured to drive the pump, and a pressure switch, including a push-button for activating and deactivating the pressure switch, movable between first and second operating positions. A housing covers the pump electric motor and pressure switch. A switch, coupled to the housing and movable between first and second operating positions is configured to move the push-button such that when the switch is in the first operating position, the push-button is in the respective first position and, when the switch is in the second operating position, the push-button is free to switch between the first and the second position.

A knob assembly with a display that displays information such as power level and a timer time, and a cooking apparatus including a knob assembly are provided. The knob assembly may include a knob coupled to an adjustment shaft configured to adjust power level and a knob ring configured to surround a periphery of the knob, configured to be rotatable independent of the knob, and provided with a display. The display may be provided at the knob ring, and information may be displayed on the display so that a user may easily manipulate the knob assembly.

A knob assembly and a cooking apparatus including a knob assembly are provided. The knob assembly may reduce defects in assembly and operation of the knob assembly caused by a tolerance of a valve shaft. The knob assembly may include a valve in which a valve shaft may be movable, a knob connected to a knob shaft coupled with the valve shaft, a knob ring that surrounds a periphery of the knob and supports the knob shaft, a support ring coupled with the knob ring, a support frame that supports an outer circumferential surface of the support ring, and a fixing frame coupled with the support frame to prevent the support ring from separating from the support frame.

A limit switch assembly for a rising-stem valve includes an operating lever actuator element mounted to an outer end of an actuator arm. An electrical switch mounted adjacent the outer end has an operating lever. When the actuator arm is in an outward position, the operating lever actuator element retains the operating lever in a first position wherein the electrical switch is in a first state, and when the actuator arm is in an inward position the operating lever is in a second position wherein the electrical switch is in a second state. An adjustment nut is mounted to the outer end adjacent the operating lever actuator element, and the operating lever actuator element and the adjustment nut are configured to be adjusted along a longitude of the actuator arm to change a distance the operating lever actuator element must travel to move the operating lever into the first position.
