Abstract

In a helicopter with the rotor blades controlled by a swash plate with a stationary part (11) and a rotary part (9) and hydraulic adjusters (4) in a stationary part of the helicopter or in a rotating system, it is proposed to fit a pump, especially a multi-cylinder reciprocating piston pump, between the stationary part (11) and the rotary part (9) of the swash plate. Besides reducing space needs, weight and costs, this provides a short, reliable oil distribution system to the consumers.
