Abstract
1,182,966. Rotary pumps. HOBOURN-EATON MFG. CO. Ltd. Sept. 8, 1967 [Sept. 16, 1966], No.41239/67. Heading F1F. A rotary hydraulic pump, as shown of the roller vane type, comprises a housing 11, Fig. 1, of sheet metal having a resiliently deflectible flange 47 directed axially inwards and subjected to hydraulic pressure transmitted to a chamber 54 communicating with the discharge side of the pump through a passage 53 in an end member 43 abutting the pump rotor 14 so that the flange 47 sealingly engages the end member 43 to prevent leakage from the housing. A sealing ring 46 is fitted between the flange and the end member and a sealing means 50 subjected to pump inlet pressure surrounds the drive-shaft 13 and seals against the end member 14. Pump discharge pressure in the chamber 54 also urges the end member 43 into sealing engagement with the rotor 14.
