Abstract

1324443 Rotary positive-displacement pumps BRITISH OXYGEN CO Ltd 15 Feb 1972 [23 Nov 1970] 55690/70 Heading F1F A vacuum pump or blower comprises a stator 2 with inlet and outlet ports 10, 12 and a rotor 4 with vanes 16 of self-lubricating material incorporating carbon fibres. The carbon fibres may be parallel to one another and in two or more plies, and are in a matrix of P.T.F.E., epoxy resin or other thermosetting or thermoplastic material. The fibres may extend radially of the rotor or parallel to its axis. A reinforcement, e.g. of expanded metal or plugs of metal, may be included in the vanes to increase their mass and/ or strength.
