Abstract

900,873. Mono pumps. MONO PUMPS Ltd. April 19, 1961, No. 14205/61. Class 110 (2). In a mono type pump a pressure relief valve is provided between the pressure and suction chambers of the pump, in the form of one or more resilient flaps produced by slits 22, 23 through the wall of the stator. The slits may be formed in the shape of a cross.
