    Abstract: A pump has a suction region, a pressure region, and a pressure space which has an outflow region. A rotor is connected to a shaft in which rotor delivery elements are displacably received. The rotor has expelling regions connected to the pressure region by way of a first fluid path. A cold starting device is prestressed into a first functional position to shutoff a second fluid path from the pressure region to the pressure space, and is configured to be displaced counter to the prestress into a second functional position to open the second fluid path. The cold starting device is arranged in its second functional position at least in regions with a relief face which faces away from the pressure region in a relief receptacle. The relief face is loaded during operation of the pump with a pressure being smaller than a system pressure in the outflow region.

    Abstract: A variable displacement pump is disclosed for hydraulic gearbox control systems, in particular a vane pump, having a variable stroke volume and having a pump regulator for outflow pressure regulation, in which the outlet pressure of the pump acts in a compensation chamber and a regulation pressure, which can be set by the pump regulator, acts in a regulation pressure chamber on an adjustable stroke ring, wherein the pressure in the regulation pressure chamber and an additional spring force adjust the stroke ring in the direction of maximum pivoting out. Additionally, a gearbox control system for automatic gearboxes, which has a primary hydraulic circuit for the elements of the gearbox that are relevant to force transmission and a primary pressure regulating valve, which opens a bypass to a secondary hydraulic circuit when the settable primary pressure is exceeded and has an additional pressure-limiting function for the primary pressure if the primary pressure continues to be exceeded, and wherein the secondary hydraulic circuit acts to cool and lubricate the gearbox, and wherein the regulation loop or regulation circuits of the pump regulation system and of the gearbox regulation system can be separated from each other by a switching valve and thus can be connected individually and independently or can be connected together.
