Embodiment Construction
[0028] exist figure 1 A pump element 10 of a hydraulic system (not shown in further detail) of a vehicle brake system for supplying brake fluid is shown in . The pump element 10 includes a cylinder 12 with a first cylinder chamber 14 , a second cylinder chamber 16 and a suction chamber 18 .
[0029] Furthermore, the pump element 10 comprises a piston 20 mounted reciprocally displaceably in the cylinder 12 . For displacement, the pistons 20 are each coupled on one end side thereof to an eccentric 22 and on the opposite end side to a return spring 24 in a pressure-transmitting manner. Furthermore, the piston 20 has a first active surface 26 in the first cylinder chamber 14 and a second active surface 28 in the second cylinder chamber 16 .
[0030] The second cylinder chamber 16 is connected to the first cylinder chamber 14 via a first line 30 , which here leads through the piston 20 and has an associated non-return valve 32 . Furthermore, a pressure line 34 for discharging t...
