An expansion valve including a valve body having an inlet, an outlet, a main flow passage extending from inlet to outlet, and a metering orifice in the at least one main flow passage. A power element controls movement of a valve member relative to the metering orifice to control flow of operating fluid passing across the metering orifice when the valve is operating in a forward flow expansion mode. The valve body includes an internal bypass flow passage that bypasses the metering orifice, and a bypass check valve is arranged internally of the valve body in the bypass flow passage. The bypass check valve is configured to open at least partially in response to operating fluid flowing in a reverse flow bypass mode in which activation of the bypass check valve opens the bypass flow passage to permit operating fluid to bypass the metering orifice in the reverse bypass mode.

A throttling device, including a tank for accommodating liquid refrigerant, with an orifice plate arranged at an outlet of the tank; a floating ball capable of floating on a liquid surface of the refrigerant; a pivot rod pivotally fixed on the tank through a pivot shaft; a connecting rod, with one end thereof fixedly connected with the floating ball, and the other end thereof fixedly connected with the pivot rod; a valve plate fixed on the pivot rod and located near an orifice of the orifice plate, wherein the valve plate is capable of adjusting a flow area of the orifice under the action of the pivot rod; and a limit piece located above the valve plate and being movable to limit the valve plate.

An electronic expansion valve and an assembly method therefor. The electronic expansion valve includes a screw rod component, a movable connection component, a valve pin component and an elastic element. One end of the elastic element abuts the movable connection component, and the other end thereof abuts the valve pin component. In the period from the valve pin component closing the valve port part to the screw rod component moving a pre-set displacement amount in the valve closing direction, the elastic element does not generate an elastic force pushing the valve pin component towards the valve port part; and in the period from the valve pin component closing the valve port part to in a case that the screw rod component moving more than the pre-set displacement amount in the valve closing direction, the elastic element generates an elastic force pushing the valve pin component towards the valve port part.

A valve assembly includes a valve body defining a cylindrical passage therein about an axis. An inlet port is defined in or near a first end of the valve body. First and second outlet ports are defined in the valve body extending radially outward from the cylindrical passage. A cylindrical valve spool having a central passage is positioned within, and sealingly engaged with, the cylindrical passage. The valve spool is moveable along the axis among: a first position wherein the inlet port is in fluid communication with the first outlet port but not the second outlet port, a second position wherein the inlet port is in fluid communication with the second outlet port but not the first outlet port, and an intermediate position between the first and second positions wherein the inlet port is in fluid communication with both of the first and second outlet ports.

A refrigerator includes a main body that has a storage chamber and a drying chamber; a thermoelectric module that includes a heat absorber and a heat dissipater; a cooling fan that circulates air in the storage chamber to the heat absorber and the storage chamber; a heat-dissipating fan that blows air to the heat dissipater; an air guide that has a passage for guiding air heated by the heat dissipater to the drying chamber; a heater that is disposed in the passage; and a damper that controls a flow of air in the passage between the heat-dissipating fan and the heater. Heat of the heat dissipater transfers to the drying chamber through the passage of the air guide and the damper, thereby being able to dry an object to be dried.

Disclosed is a valve having: a body that has an upstream end and a downstream end; an inlet orifice; a plurality of passages including: a first outlet passage extending into the body from the downstream end to a location intermediate the upstream end and the downstream end of the body; an inlet passage extending into the body from the upstream end of the body, the plurality of passages extending along mutually parallel axes, wherein the axes are offset radially and/or circumferentially from each other; and the inlet passage being formed in an insert configured for axially moving to: fluidly engage with the first outlet passage to define a continuous fluid passage between the upstream end and the downstream end of the body, wherein: an output flow rate through the body increases or decreases depending on an axial location of the insert.
