Abstract:
The present disclosure relates to a piston pump assembly comprising a piston with a variable stroke and to a hydraulic braking system comprising the same. The piston pump assembly comprises at least: a rotatable drive shaft defining an axis of rotation of the rotatable drive shaft; a cam disposed on the drive shaft; and the piston biased toward the cam and configured to reciprocate along a piston axis for displacing a hydraulic fluid. The cam is movable relative to the piston axis and is selectively placed in one of a first position at a first distance from the piston axis and a second position at a second distance from the piston axis; and wherein the cam comprises at least two portions each of which has, at a given position of the cam relative to the piston axis, a different non-circular cross section in a plane perpendicular to the axis of rotation and/or a different eccentricity with respect to the axis of rotation, the at least two portions of the cam comprising at least a first cam portion having a first non-circular cross section and/or a first eccentricity, and a second cam portion having a second non-circular cross section and/or a second eccentricity.

Claim (Index 12):
The piston pump assembly according to  claim 1 , further comprising a housing including a cam chamber, wherein the cam is movably disposed within the cam chamber and in sliding sealing engagement with an inner wall of the cam chamber, and wherein the cam chamber is configured to be at least partially filled with a hydraulic fluid at least on one side of the cam, such that the cam is configured to be moved relative to the piston axis by controlling a quantity of fluid and/or a hydraulic pressure within the cam chamber.
