A tap group comprising a tap body provided with at least one dispensing exit, an operating lever or knob, a regulation member of the parameters of the flow of water to be dispensed (the parameters including the temperature and/or the flow of water and/or the direction of the flow), and a transmission including gears which operatively connect the operating lever or knob to said regulation member of the flow of water. Advantageously, the gears create a gear ratio between the operating lever or knob and a control rod of the regulation member of the parameters of the flow of water, so as to reduce the rotation of the control rod of the regulation member for the same rotation of the operating lever or knob. The tap group also includes a ring-nut provided with at least one indicator and/or a reference index of the parameters of the flow to be dispensed.

A faucet configured for touchless actuation that includes a spout; a mechanical valve configured to move between an open state and a closed state and having a member radially movable between an open position and a closed position in response to operation of the mechanical valve between the open state and the closed state; an electronic valve configured to move between an open state and a closed state; and a system configured to detect and communicate a state of the faucet in response to the position of the member.

A hydraulic system includes a hydraulic valve, a load-holding valve arrangement, a flow-control valve arrangement, a working pressure sensor, a differential pressure sensor, and a speed sensor. The load-holding valve arrangement includes first and second load-holding valves connected to opposite ends of the hydraulic cylinder. The flow-control valve arrangement includes a directional flow-control valve and a hydraulic pump. The differential pressure sensor measures pressure over the load-holding valve arrangement. A desired extension or retraction speed of the hydraulic cylinder is controlled by adjusting the position of the directional flow-control valve, the first load-holding valve and the second load-holding valve based on a measured working pressure in the hydraulic system and a measured speed of the hydraulic cylinder or a differential pressure over the load-holding valve arrangement.

A valve device includes a body having a fluid passage formed therein, a valve element configured to open and close the fluid passage, a stem arranged to be configured to move toward and away from the valve element to cause the valve element to open and close the fluid passage, an actuator having a casing coupled to the body, and drive unit arranged in the casing to drive the stem by an operating fluid supplied from outside, and a valve mechanism provided at the casing and configured to open and close a passage of the operating fluid to the drive unit.

A water delivery device includes a body, a user interface, a micro-mixing valve, first and second capacitive sensors, and a controller. The body includes a base and a spout. The user interface is provided on the spout. The micro-mixing valve is contained within the body and is in fluid communication with a hot water source and a cold water source. The first capacitive sensor is provided below the user interface. The second capacitive sensor is provided below the user interface and is spaced apart from the first capacitive sensor. The controller is operatively connected to the first capacitive sensor, the second capacitive sensor, and the micro-mixing valve. Each of the first and second capacitive sensors is configured to be independently activated by a user to transmit a signal to the controller to increase or decrease a temperature of a flow of water flowing from the micro-mixing valve.

A multi-split air-conditioner and an outdoor unit system thereof are provided. The outdoor unit system includes: a compressor (1) having a gas outlet (a) and a gas inlet (b); an outdoor heat exchanger (2) having an inlet (c) and an outlet (d); a switching assembly (3) having first to sixth ports, wherein the first port (e) is connected with the gas outlet (a) of the compressor (1), the second port (f) is connected with the gas inlet (b) of the compressor (1), the third port (g) is connected with the inlet (c) of the outdoor heat exchanger (2), the fourth port (h) is connected with the outlet (d) of the outdoor heat exchanger (2), the fifth port (i) is connected with an inlet pipe (4) and the sixth port (j) is connected with an outlet pipe (5).

A mixer water faucet for installation through a bore in a work surface in proximity to a water supply, includes a stationary housing extending transversely through the bore; a faucet body mounted onto the housing, rotatable relative thereto; a main spout and an auxiliary spout extending from the housing; a main water supply hose for conveying water to the main spout and an auxiliary water supply hose for conveying water to the auxiliary spout, the main water supply hose and the auxiliary water supply hose extending through the housing; and a diverter for selectably directing a supply of water to the main spout and the auxiliary spout.

A free-standing faucet which includes a valve assembly, a spout, an inlet tube set, and a free-standing casing tube, a spray holder, and a spray is revealed. The valve assembly consists of a housing, a mixing valve, and a diverter, and a handle. The housing is composed of a mixing valve chamber in which the mixing valve is mounted, a pipe joint connected to the inlet tube set, a connection portion formed on one side of the pipe joint close to the mixing valve chamber, a first cold water channel, and a first hot water channel. The first hot and cold water channels are formed inside the pipe joint and communicating with the connection portion and the inlet tube set. An adapter is connected to the connection portion and having second cold and hot water channels. Thereby the mixing valve can be assembled and positioned easily, securely and accurately.
