Abstract (en)
[origin: EP0886068A2] The pump has two gear wheels (Z1,Z2), interlocked with each other, each fitted to spindles (W1,W2). Each of these is driven by a drive unit (AE1,AE2). They are controllable through control modules (SE1,SE2) in such a way that the spindles turn with an angular velocity (w1,w2). The control modules are symetrically designed, so that each control module is fitted with control units (KE1,KE2) that can be coupled one with the other through a data line (DL).
