Abstract

907,111. Gear pumps. DUNLOP RUBBER CO. Ltd. Feb. 2, 1959 [Feb. 13, 1958], No. 4698/58. Class 110 (2). A gear pump has a number of gear teeth 3a, 4a slotted to cyclically establish intercommunication between the inlet and outlet sides of said pump, the arrangement being such that the pump will supply a pulsating flow of fluid to a spring retractable hydraulic actuator 9, 10.
