摘要： A control of an electromagnetically driven reciprocating piston influences the speed of a magnet armature by switching the voltage supplied to the electromagnet dependent on the position of the magnet armature. In the process, the position of the magnet armature should not be measured but rather determined from state variables of the electromagnet. This is achieved in that a processor (11) calculates the electric resistance of the magnet coil (5) from the electric voltage values and electric current values measured by the measuring device (13), calculates the temporal change of the linked magnetic flux in the electromagnet (2) from the electric voltage, the electric current, and the electric resistance of the magnet coil (5), calculates the linked magnetic flux in the electromagnet (2) from an older magnetic flux and the temporal change, determines the position of the magnet armature (7) from the linked magnetic flux in the electromagnet (2) and the electric current flowing through the magnet coil (5), and switches the electric voltage at the magnet coil (5) by means of the switch device (12) depending on the position of the magnet armature (7). Reciprocal piston pumps of the aforementioned type and the electric control thereof are used to pump and/or meter fuel and reagents in vehicles and mobile work machines.

摘要： 1. Reciprocating piston pump with input-side flow rate limitation 2. Abstract a. Problem addressed: a cost-effective reciprocating piston pump should have an input-side flow rate limitation and should also function reliably for fluids of different composition, including fluids contaminated by small particles. b. Solution: a first displacement chamber (3) is connected to an inlet (9) via a throttle (8), wherein the throttle (8) is closed by a seal (24) which is connected to a piston (5) if the piston (5) is located in the inlet-side end position thereof, and wherein the force of a restoring spring (11) is greater than the compressive force which arises from the pressure at the inlet (9) and on the active surface (25) of this pressure between the throttle (8) and the seal (24) if the seal (24) abuts the throttle (8). c. Application: The reciprocating pump according to the invention is used for draining or suctioning fluid out of a filter housing or a water separator, preferably on diesel engines in vehicles.
