A device for controlling a flow rate and expanding a fluid in a fluid circuit. The device is formed with an enclosure and a valve element arranged inside the enclosure. The valve element which is arranged movably in a linear movement in the direction of a longitudinal axis relative to the enclosure has a sealing surface and a control area formed at a first end face of the valve element and arranged adjacent to the sealing surface in the axial direction. The sealing surface is formed as a lateral surface of a straight circular cylinder with a constant outer diameter. An outer diameter of a surface of the control area corresponds to the outer diameter of the sealing surface. The control area has throughflow apertures and at least one control aperture. The valve element in the control area is formed with a substantially hollow circular cylindrical-shaped wall.

Device for controlling a flow rate and expanding a fluid in a fluid circuit and method for operating the device

A device for controlling a flow and distributing a fluid, in particular a refrigerant, in a fluid circuit. The device exhibits a housing with connections for connection to fluid lines that are connected to one internal volume of the housing via a pass-through opening, and one valve element that is arranged in the internal volume of the housing and exhibits a drive element for moving the valve element relative to the housing. The valve element exhibits one pass-through opening and is mounted in such a way that it can be moved linearly in the axial direction along a longitudinal axis such that a passage for the fluid is opened between a first connection produced as an inlet and a second connection produced as a primary outlet or a third connection produced as a secondary outlet.

Device for controlling a flow and distributing a fluid in a fluid circuit

A device for controlling a flow rate and expanding a refrigerant in a refrigerant circuit of an air conditioning system of a motor vehicle. The device has a housing, an actuating element and a valve element arranged in the interior of the housing and aligned in an axial direction, a valve seat element, and at least one sealing element. The valve element is arranged within the valve seat element and sealed towards the housing and the valve seat element via the at least one sealing element, and is formed in a circular cylindrical shape with a sealing area formed on a lateral surface. The inner surface of the sealing element forms a sealing seat in conjunction with the sealing area of the valve element.

Device for controlling a flow rate and expanding a fluid in a fluid circuit

A device for regulating a throughflow and distributing a fluid in a fluid circuit, in particular a refrigerant. The device has a housing with ports for connecting to fluid lines which are connected to at least one inner volume of the housing designed as a valve chamber via a respective through opening, and at least one valve element arranged in the valve chamber with a drive element for moving the valve element relative to the housing. The at least one valve element is mounted such that it can be displaced in a linear manner in the axial direction along a longitudinal axis such that a passage for the fluid is opened between a first port designed as an inlet and a second port designed as a first outlet and/or a third port designed as a second outlet.

Device for regulating a throughflow and distributing a fluid in a fluid circuit

A valve () is introduced for a heat pump system in a motor vehicle, with at least one inlet (), at least two outlets () and a valve element () which comprises at least one throughlet () and at least one expansion recess () that can be brought into fluidic connection with at least one outlet ().

3-2 way expansion valve

A heat-exchanger including a device for separating oil from a coolant-oil mixture and cooling the oil and cooling and/or liquefying the coolant. The heat exchanger features a first area cooling and/or liquefying the coolant, and a second area cooling the oil. The heat exchanger further features at least two manifolds. The first area of the heat exchanger features flow channels guiding the coolant, and the second area of the heat exchanger features flow channels guiding the oil. The flow channels extend between the manifolds. Each of the flow channels has a respective outside flooded by a heat-absorbing fluid.
