A fluid system for a continuously variable transmission includes a first pump, a first actuation unit, a first line section, a second actuation unit, and a second line section. The first pump has a first sub-pump and a second sub-pump. The first actuation unit is assigned to a first disc set of the continuously variable transmission and the second actuation unit is assigned to a second disc set of the continuously variable transmission. The first line section fluidically connects the first pump to the first actuation unit and the second line section fluidically connects the first pump to the second actuation unit. The second sub-pump has a first connection that can be selectively fluidically connected to the first actuation unit via the first line section, or the second sub-pump has a second connection that can be selectively fluidically connected to the second actuation unit via the second line section.

A vortex reservoir for separation of an aerated portion of a hydraulic fluid includes an upper chamber and a lower chamber, in fluid communication with the upper chamber, having a lower chamber sidewall. The lower chamber includes a lower lower chamber and an upper lower chamber. The lower chamber includes a lower chamber partitioning plate. The lower chamber partitioning plate is located between the lower lower chamber and the upper lower chamber. The lower lower chamber is in fluid communication with the upper lower chamber via a gap between the lower chamber partitioning plate and the lower chamber sidewall.

A portable, battery-powered hydraulic unit for hydraulic rescue tools, in particular for spreading or cutting tools, as well as a rescue tool equipped therewith, are disclosed. The hydraulic unit includes at least one hydraulic pump, a hydraulic tank, a compensation device for hydraulic fluid, a manually operated hydraulic control valve, an electromechanical interface for on-demand coupling and decoupling of at least one battery pack, a mechanical-hydraulic interface for connecting a hydraulic tool, and an electric motor operable by the electrical energy of the battery pack for driving the hydraulic pump. The electric motor is formed by a disc-shaped motor whose axial length extending in parallel to the longitudinal axis of its output shaft is shorter than its outer diameter.
