Abstract
A housing of a multiway valve contains several inlets and outlets and a chamber containing several valve seats, each of which is allocated to one of the outlets. A closing device can be displaced between the valve seats. A cylinder contains a cylinder chamber having a fluid. A heating device is provided for heating the fluid and a plunger is provided that can be displaced in the cylinder by the pressure of the fluid. By its displacement, the plunger is able to dislodge the closing device from one of the valve seats.
Claims15
A multiway valve, comprising:
- a housing having a plurality of inlets and outlets and a chamber formed therein;
- a plurality of valve seats each associated with one of said inlets or outlets;
- a closing member disposed in said housing and movable between said valve seats;
- at least one cylinder having a fluid-containing cylinder chamber formed therein and disposed in said housing;
- a heating device for heating said cylinder;
- and
- a plunger movable in said cylinder under pressure of a fluid, said plunger, by virtue of its movement, being capable of displacing said closing member from one of said valve seats to another of said valve seats.
A fluid circuit, comprising:
- a supply circuit supplying heating energy;
- and
- a multiway valve receiving a fluid in at least a partially liquid state, said multiway valve containing:
- a housing having a plurality of inlets and outlets and a chamber formed therein;
- a plurality of valve seats each associated with one of said inlets or outlets;
- a closing member disposed in said housing and movable between said valve seats;
- at least one cylinder having a fluid-containing cylinder chamber formed therein and disposed in said housing, said cylinder chamber receiving the fluid;
- a heating device associated with said cylinder for heating said cylinder, said heating device receiving the heating energy from said supply circuit for evaporating the fluid in said cylinder chamber of said cylinder;
- and
- a plunger movable in said cylinder under pressure of the fluid, said plunger, by virtue of its movement, being capable of displacing said closing member from one of said valve seats to another of said valve seats.
A refrigerator, comprising:
- a refrigerant circuit;
- and
- a multiway valve disposed in said refrigerant circuit, said multiway valve, containing:
- a housing having a plurality of inlets and outlets and a chamber formed therein;
- a plurality of valve seats each associated with one of said inlets or outlets;
- a closing member disposed in said housing and movable between said valve seats;
- at least one cylinder having a fluid-containing cylinder chamber formed therein and disposed in said housing;
- a heating device associated with said cylinder for heating said cylinder;
- and
- a plunger movable in said cylinder under pressure of a fluid, said plunger, by virtue of its movement, being capable of displacing said closing member from one of said valve seats to another of said valve seats.
