Document Type and Number:
WIPO Patent Application WO/2021/125566
Kind Code:
A1
Abstract:
The invention relates to a device (1) for controlling a flow rate and expanding a fluid in a fluid circuit. The device (1) is formed with an enclosure (2) and a valve element (6) arranged inside the enclosure (2). The valve element (6) which is arranged movably in a linear movement (6a) in the direction of a longitudinal axis relative to the enclosure (2) has a sealing surface (11a) and a control area (16) that is formed at a first end face of the valve element (6) and arranged adjacent to the sealing surface (11a) in the axial direction. The sealing surface (11a) is formed in the form of a lateral surface of a straight circular cylinder with a constant outer diameter. An outer diameter of a surface of the control area (16) corresponds to the outer diameter of the sealing surface (11a). In addition, the control area (16) has throughflow apertures (14) and at least one control aperture (15). The valve element (6) in the control area (16) is formed with a substantially hollow circular cylindrical-shaped wall. The invention also relates to a method for operating a device (1) for controlling a flow rate and expanding a fluid in a fluid circuit.
