摘要： An example valve includes: a plurality of ports comprising: a first port, a second port, and a third port; a spool configured to block fluid flow from the first port to the third port while allowing fluid flow from the third port to the second port when the valve is in an unactuated state; a spring applying a biasing force on the spool in a proximal direction, wherein when the valve is actuated, the spool moves in a distal direction against the spring, thereby allowing fluid flow from the first port to the third port while blocking fluid flow from the third port to the second port; and a turbine configured to rotate as fluid flows from the first port to the third port when the valve is in an actuated state.

摘要： A guide frame for a four-way reversing valve includes a frame body. Both ends of the frame body include a connecting portion, respectively. The connecting portion includes a first bending member and a second bending member, and the directions of bending of the first bending member and of the second bending member are opposite. The connecting portion includes a reinforcing member. The reinforcing member includes a first reinforcing plate and a second reinforcing plate. The first reinforcing plate is connected to the inner side of the first bending member by welding and the second reinforcing plate is connected to the inner side of the second bending member by welding. The connection strength of the connecting portion is increased, such that the guide frame is less likely to deform or break.

摘要： A water conditioning system including a first valve controller adapted to control a first valve to place a first tank into an in service mode, a standby mode, and a regeneration mode, a flow meter adapted to communicate a flow rate value to the first valve controller, and a second valve controller adapted to control a second valve to place a second tank into one of the in service mode, the standby mode, or the regeneration mode, wherein the second valve controller is in communication with the first valve controller and is adapted to place the second tank into the in service mode if the flow rate value is above a threshold flow rate value, and wherein the second valve controller is further adapted to place the second tank into the in service mode if the first tank is depleted, independent of the flow rate value.

摘要： A hydraulic oil control valve includes an outer sleeve, an inner sleeve and a spool. The outer sleeve includes: a threaded portion, which is fixed to a camshaft; a projection, which is fixed to a phase changer; and ports, which are formed at a peripheral surface of the outer sleeve between the threaded portion and the projection. The inner sleeve includes: ports, which are communicated with the ports of the outer sleeve; an oil port; an axial groove; and an enlarged diameter portion, which is located on one side of the projection where an insertion opening of the outer sleeve is placed. The spool includes: land portions, which are configured to slide along an inner peripheral surface of the inner sleeve and are located at an outer periphery of the spool at a location that is on another side of the projection where the threaded portion is placed.

摘要： 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.

摘要： A multi-port rotary disc valve includes a valve housing having a sidewall, a lid that closes a first end of the sidewall and a base that is disposed at a second end of the sidewall. A valve chamber is defined by the base, the lid and the sidewall. The housing includes valve ports that communicate with the chamber. A diverter assembly is disposed in the chamber and is configured to control fluid flow through the valve housing. The diverter assembly includes a first part including first through openings and a second part that is axially aligned with the first part, the second part including second through openings. The diverter assembly includes an elastic element disposed between the first diverter part and second diverter part, the elastic element biasing the first diverter part toward the lid and the second diverter part toward the base.
