Abstract

978,916. Axial-flow fans. ETABLISSEMENTS BERRY. Aug. 13, 1963 [Dec. 8, 1962], No. 31983/63. Heading F1C. [Also in Division G3] A control device for varying the pitch of the blades 12 on a fan comprises an hydraulic or pneumatic jack 22 mounted of the shaft 10 of the fan and fixed against angular rotation. The cylinder 23 is fixed to a sleeve 31 which is mounted on the shaft through a bearing 30, the bearing being fixed axially. The jack comprises two pistons 28, 29 which are connected to rods 34 and a sleeve 35, the sleeve 35 being mounted on a so called bell member 21 through bearings 32 which prevent relative axial movement between the piston and bell member. The bell member is slidable on the shaft 10. Fluid pressure is admitted to the jack by a control valve 38 to cause movement of the bell member 21 which varies the pitch of the blades through crank arms 19. Rods 41 provide a feedback to the valve 38.
