Abstract

882,248. Gear pumps. WIGGERMANN, G., and REINERS, W. Nov. 26, 1957 [Dec. 11, 1956], No. 36801/57. Class 110 (2). In a gear pump assembly comprising two gear pumps A and B having a common drive and an infinitely adjustable output, the gear pumps are mounted in parallel with intake and delivery conduits 29, 30, arranged as shown, the delivery direction being controlled by levers 8, 8<SP>1</SP> and the circuit being provided with at least one change-over mechanism 28. For details of the tooth construction the Specification should be referred to.
