1. A controlling device for controlling a fluid mass flow for a compressing device for compressing a gaseous fluid from a low pressure level to a high pressure level, the controlling device comprising:
a housing with a plurality of fluid connections acted upon at different pressure levels and a closure element which is arranged such that it can be moved in a translatory manner within the housing along a longitudinal axis, with effective surfaces assigned to the fluid connections, wherein the closure element is formed such as to regulate a flow cross-section of a flow path formed such that it extends between a first one of the fluid connections and a second one of the fluid connections, wherein the controlling device for controlling the fluid mass flow has a receiving element for receiving the closure element, wherein a primary segment is arranged to be completely surrounded by the receiving element as a first section of the closure element, and a secondary segment is arranged to be completely surrounded by the housing as a second section of the closure element and the receiving element is arranged to be completely surrounded by the housing, wherein the secondary segment of the closure element is sealed to the housing via at least one first sealing element and the primary segment of the closure element is sealed to the receiving element via at least one second sealing element as well as the receiving element is sealed to the housing via at least one third sealing element, respectively in a fluid-tight and pressure-tight manner, wherein a third one of the fluid connections of the housing is formed to be acted upon by the fluid at the low pressure level.
