The invention relates to a valve for controlling a coolant circuit of a refrigerating system, having a housing, which has at least one inlet opening and at least one outlet opening, having a regulating chamber provided in the housing, which extends between the at least one inlet opening and the at least one outlet opening, having a valve arrangement, which is insertable at least partially into the regulating chamber, having a rotary slide arrangement, arranged in the regulating chamber, which has a control disc, which is rotatable in relation to the at least one rotary slide support, the at least one rotary slide support is provided non-rotationally to the housing and the at least one rotary slide support is mounted floatingly to the housing.

Valve for controlling a coolant circuit

A multi-way valve for controlling a refrigerant circuit of a refrigeration system with a heat pump function, having a housing which has two mutually opposite end faces which each comprise an insertion opening to which a regulating chamber is connected, having multi-way valve arrangements which can each be inserted in the regulating chamber, the multi-way valve arrangement comprising at least one base body and a rotary slide valve arrangement, with in each case one connection in the housing, which open into the respective regulating chamber, and with at least further connections in the housing, which open into at least one channel which extends between the regulating chambers.

Multi-way valve for a control of a refrigerant circuit

The invention relates to a shaft passage and a valve having such a shaft passage, as well as a method for producing a shaft passage, in which the shaft () has at least one drive portion () to which a drive for controlling the shaft () can be connected and has a connecting portion () opposite the drive portion (), to which an actuating member () can be connected, and an inner shaft portion () in the through-bore () extending at least partially in the through bore (), and having an inner shaft seal () to which an operating pressure of a medium to be controlled by the actuating member () is applied, and having a fluid shaft seal () which extends in the direction of the drive portion (), and which is arranged between the inner shaft seal () and the outer shaft seal (), wherein the fluid shaft seal () is formed between the through bore () and the inner shaft portion () of the shaft () and is pressure-relieved against an operating pressure of the medium to be controlled.
