1. A device for feeding a liquid-fuel burner, comprising a pump with a rotary piston (20) provided with a cut-away portion (22) and accommodated in a pressure tight manner in a housing (10) itself provided with an inlet port (11) and a delivery port (12) adapted to communicate periodically and alternately during rotation of the piston with the cut-away portion there of, and a cam mechanism (13, 14, 23) interposed between the housing (10) and the rotary piston (20), and defining internally of the housing (10) a variable volume of space communicating with the cut-away portion of the piston, and a motor (27) for driving the piston in rotation, characterized by the fact that the piston (20) is constituted by the motor shaft, on which the housing (10) is slidingly mounted, whilst being resiliently urged towards the motor shaft (20) by a weak return spring (15), whilst flexible connections (11a, 12a) connect the inlet and delivery ports of the body, substantially rotationally held, to fixed parts. |
