1. A device for regulating a throughflow and distributing a fluid in at least one fluid circuit, the device comprising a housing with a first port, a second port, and a third port 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 at least one valve element relative to the housing, wherein the at least one valve element is mounted such that it can be displaced in a linear manner in an axial direction along a longitudinal axis such that a passage for the fluid is opened between the first port designed as an inlet and the second port designed as a first outlet and/or the third port designed as a second outlet, and wherein the at least one valve element is designed in the form of a cylinder oriented in the axial direction, with a first section and a second section which are arranged in the axial direction in a manner spaced apart from one another and are connected to one another via a coupling element, wherein the device has at least a first pressure chamber and a second pressure chamber which are respectively designed as a region of the valve chamber at an end face of the at least one valve element oriented in the axial direction, wherein at least one of the first pressure chamber and the second pressure chamber is designed such that it is fluidly connected to the through opening of the first port of the housing and the first pressure chamber and the second pressure chamber are fluidly connected to one another, and wherein the first pressure chamber and the second pressure chamber are designed such that they are fluidly connected to the through opening of the first port of the housing via a respective connection channel formed inside a wall of the housing separately from the valve chamber.
