LINEAR DRIVE AND PISTON PUMP ARRANGEMENT
First Claim
1. A linear drive, comprising:
- a first electromagnetic drive device;
a second electromagnetic drive device; and
a drive piston configured to be moved in an axial direction by the drive device,wherein the first drive device and the second drive device are each in the form of a reluctance drive device, andwherein each of the reluctance drive devices has (i) a stator with a coil winding, the coil winding engaging around the drive piston in a circumferential direction, and (ii) a coil core which has a coil receptacle, open in a radial direction toward the drive piston, for the coil winding.

Abstract
A linear drive, in particular for a piston pump, includes a first electromagnetic drive device, a second electromagnetic drive device, and a drive piston configured to be moved in an axial direction by the drive devices. The first drive device and the second drive device are each in the form of a reluctance drive device. The reluctance drive devices each have a stator with a stator coil that engages around the drive piston in a circumferential direction. The reluctance drive devices each also have a coil core with a coil receptacle, open in a radial direction toward the drive piston, for the coil winding. A piston pump arrangement includes the linear drive.
