摘要： A pressure supply device for prioritised volume flow splitting, in particular in mobile working machines, includes at least one adjusting pump (2) controllable by an LS signal as main pump, a constant-displacement pump (4) as an auxiliary pump, and two pressure balances. A system is supplied primarily, in particular in the form of steering hydraulics (PL), which outputs an LS signal. A system is supplied secondarily, which outputs a further LS signal, in particular in the form of working hydraulics (PA). A further system is supplied hydraulically, in particular in the form of brake hydraulics (PB). One pressure balance (DW1) is used to supply the system (PL) to be supplied primarily and/or the further hydraulic system (PB), the other pressure balance (DW2) is used to supply the system (PL) to be supplied primarily and/or the system (PA) to be supplied secondarily, The respective pressure balance (DW1, DW2) can be activated by an LS signal in such a way that the constant-displacement pump (4) is also used to supply the system (PA) to be supplied secondarily.

摘要： An electromechanical brake pressure generator for a hydraulic braking system of a vehicle, including a threaded drive system for converting a drive-side rotary motion into a translatory motion for brake pressure generation. The system includes a spindle rotatable via an electric motor, a spindle nut cooperating with a thread of the spindle so the spindle nut is axially displaceable with a rotation of the spindle and a brake fluid is loadable or relievable, and a housing which, together with the spindle nut, forms an anti-twist protection which secures the spindle nut against twisting during rotation of the spindle. The spindle nut forms at least one spindle nut reference surface, which cooperates with at least one stop surface, which is stationary with respect to the housing, in a relief end position of the spindle nut in such a way that an instantaneous axial position of the spindle nut is determinable therefrom.

摘要： A pedal feel emulator comprises a housing extending along a center axis between a closed end and an opened end and defining a chamber extending therebetween. A first piston is slidably disposed in the chamber. The first piston defines a compartment in fluid communication with the chamber. A second piston is slidably disposed in the compartment. A spring seat extends radially outwardly from the second piston. A first elastic member is located in the chamber extending between the spring seat and the closed end. A second elastic member is located in the compartment and extending between the spring seat and the first piston. A third elastic member is located between the second piston and the first piston. A brake system including the pedal feel emulator is also disclosed herein.

摘要： A simulator valve includes a housing having a pedal simulator passage and a master cylinder passage extending therethrough. The master cylinder passage is located longitudinally between the first housing surface and the pedal simulator passage. An armature is located at least partially within the housing for selective longitudinally reciprocating motion with respect thereto between first and second armature positions. A poppet is located within the housing for selective longitudinally reciprocating motion with respect thereto between first and second poppet positions. The poppet defines a first valve and a second valve the poppet includes a poppet bore extending longitudinally therethrough and selectively occluded by the first valve. A damped flow fluid path selectively permits fluid communication therethrough from the master cylinder passage to the pedal simulator passage. A free flow fluid path selectively permits fluid communication therethrough from the pedal simulator passage to the master cylinder passage.
