A torque transfer assembly includes a drive shaft and a driven shaft and a dielectric connector positioned between. The connector connects the drive shaft and the driven shaft and includes a body of dielectric material defining an insulating barrier between the drive and the driven shaft. The connector includes a dielectric barrier body having a first side from which a protrusion extends, the protrusion configured to engage in a correspondingly shaped recess formed in one of the drive shaft or the driven shaft, and a second side, opposite the first side, in which is formed a recess shaped to receive a correspondingly shaped protrusion extending from the other of the drive shaft or the driven shaft, the connector providing a dielectric barrier between the drive shaft and the driven shaft.

A method of forming a dielectric barrier and torque transfer member between a drive shaft and a driven shaft of a torque transfer assembly. The method includes assembling the drive shaft and the driven shaft in axially adjacent relationship to one another, the drive shaft and the driven shaft each having a recess formed therein such that when the shafts are assembled, the recesses cooperate to define a chamber extending across the interface between the drive and driven shaft and into the interior of both the drive and the driven shaft. The method further includes injecting a dielectric adhesive or resin material into the chamber to fill the chamber and to extend across the interface between the drive and the driven shaft, and curing the dielectric material to form a dielectric barrier between and to provide torque transfer between the drive and the driven shaft.

A flush valve includes a valve housing defining a fluid passageway between a fluid inlet and a fluid outlet. The fluid passageway includes a diaphragm valve seat disposed between the fluid inlet and the fluid outlet. The flush valve additionally includes a diaphragm assembly including a diaphragm and a disc. The diaphragm includes a primary opening and a bypass opening. The primary opening receives the disc therein and the bypass opening allowing water under pressure supplied to the fluid inlet to pass from a fluid inlet side of the diaphragm into a chamber in the fluid passageway. The flush valve additionally includes a relief valve configured to selectively control fluid flow from the chamber to the fluid outlet. The relief valve comprises a stationary valve element and a rotatable valve element each having at least one opening and being rotationally positionable relative to one another to regulate fluid flow.

A ball valve includes a housing and has an inlet port, an outlet port and a central ball chamber. A ball member is received within the ball chamber and has a shaft connected to a motor such that the ball member can be rotated. The ball member is movable between a closed position at which it blocks fluid connection between the inlet port and the outlet port and to an open position at which a central passage in the ball member communicates the inlet port to the outlet port. A seal is mounted for movement with the ball member to provide a seal against the housing. A ball valve system is also disclosed.

Integrated flow meter and control valve (1) including a flow tube (11); a substantially watertight meter housing (12) providing a compartment (121), extending from the flow tube; a metering unit (139 arranged inside the compartment for measuring the flow of a medium flowing though the flow channel, and an electrical valve actuator (18) arranged inside the compartment and adapted to control a flow control element (19) arranged inside the flow channel, wherein that meter housing is formed as an integrated part of the flow tube with the compartment having a primary opening (124) for insertion of the metering unit and a secondary sealable opening (125) for insertion of the electrical valve actuator.

A coolant control valve is provided that includes at least one actuator, a first rotary valve body and a second rotary valve body, each rotary valve body driveably connected to the at least one actuator. The second rotary valve body is arranged non-coaxially to the first rotary valve body.

In a valve device, a rotor has a hole closing portion configured to increase or decrease a covered area of a first flow hole of a stator in response to rotation of the rotor. The hole closing portion has a hole closing portion edge which extends in a radial direction of a predetermined axis and is located at a circumferential end of the hole closing portion on one side in a circumferential direction. In a state where the first flow hole is closed by the hole closing portion, when the rotor is rotated toward another side, which is opposite to the one side in the circumferential direction, the hole closing portion begins to open the first flow hole. The first flow hole has a one-side hole edge which is located at a circumferential end of the first flow hole on the one side and extends in the radial direction.

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.

A housing has a housing main body and an outlet port. The housing main body includes a cylindrical housing inner wall that defines an internal space therein. The outlet port fluidly connects the internal space and an outside of the housing main body to each other. The valve has a valve body rotatable about an rotation axis along a rotation axis of the cylindrical housing inner wall. The valve is configured to selectively open and close the outlet port depending on a rotation position of the valve. The housing inner wall is formed such that a distance between the housing inner wall and the axis of the housing inner wall varies in a circumferential direction.

In a first embodiment, a ventilator has a housing with a first fixed port and a rotatable shutter configured to cooperate with the housing to enclose an interior of the housing. The shutter has a first orifice at a first radial distance from its axis of rotation. A stationary plate abuts the shutter and includes a first stationary orifice configured to at least partially align with the first orifice of the shutter over a first rotational distance of the shutter. In this way, the first orifice and the first stationary orifice form a first variable port. The stationary plate may have a second stationary orifice and the shutter may have a second orifice configured to at least partially align with the second stationary orifice over a second rotational distance of the shutter.
