摘要： A capacity control valve includes: a valve body having first communication passages, second communication passages, third communication passages, and a main valve seat; a valve element having an intermediate communication passage, a main valve portion and an auxiliary valve portion; a pressure-sensitive element disposed in the valve body; a solenoid that drives a rod; a first biasing member that biases in a valve closing direction of the main valve portion; and a second biasing member that biases in a valve opening direction of the main valve portion, wherein the rod moves relative to the valve element to press the pressure-sensitive element. The capacity control valve can efficiently discharge a liquid refrigerant and can decrease a driving force of a compressor during a liquid refrigerant discharge operation.

摘要： A multi-control valve unit includes a housing with built-in spools that are parallel to each other. The housing includes pilot chambers formed therein, the pilot chambers corresponding to both ends of the spools. Solenoid proportional valves are mounted to the housing, such that the solenoid proportional valves are connected to the respective pilot chambers. A hydraulic pressure generator is mounted to the housing, such that the hydraulic pressure generator is connected to the solenoid proportional valves. The hydraulic pressure generator includes an electric motor and a pump.

摘要： The present disclosure provides an electric water diverter, which includes a controller, a brushless DC motor, a core and a T-shaped body. The controller is electrically connected to a fixed Hall PCB circuit board and the brushless DC motor in turn. The brushless DC motor has a rotating shaft detachably connected to the core via a connector, which is also embedded with a magnet cooperating with the Hall PCB circuit board. The Hall PCB circuit board obtains a relative position signal of the rotating shaft through Hall induction and feeds the relative position signal back to the controller. A user controls the brushless DC motor to perform phase rotation through the controller and drive the connector and the core to selectively rotate forward or backward relative to the T-shaped body. Thereby, stepless adjustment of water flow from water outlet is achieved.

摘要： Three-port latching valves have a housing with a first port, a second port, and a third port in controlled fluid communication with one another by three, individually electronically controllable magnetically latching valves for a combination of five different flow options. Each valve has a solenoid with an armature movable between an open position and a closed position, a poppet valve connected to the armature, a permanent magnet fixedly seated at a position for magnetically latching the armature in the open position, and a spring positioned to bias the poppet valve closed when the armature is in the closed position. The spring has a pre-selected spring rate that mechanically relieves pressure if the spring rate is exceeded. The armature is movable to the open position after a pulse of voltage to the solenoid and is in an unpowered state after translation to either of the open position or the closed position.
