    摘要: A system (10) having a control plate (15) for controlling the pitch of the blades (5) of a propeller, a power block (20), and a directional control valve (30) for feeding said power block (20) with fluid. The power block (20) is sealed and includes at least a body in which at least one piston (22) that is secured to a piston rod (25) projecting from said body (21) is movable in translation, a repeater rod (50) connecting said piston rod (25) to said control plate (15). The control valve (30) is sealed and comprises a stationary manifold (35) and a movable manifold (40) that is movable in rotation, said stationary manifold (35) being controlled by a control lever (31) connected by repeater means (32) to said repeater rod (50). A respective pipe (60) connects each chamber (23, 24) of said power block (20) to said movable manifold (40).

    摘要: A control lever (10) provided with a stick (11) extending axially from a stand (11′) towards grip means (11″) and with a carrier structure (20) for said stick (11) that is hinged about a first hinge axis (AX1) and about a second hinge axis (AX2). The control lever (10) includes phasing means (30) constrained to move in rotation with said stick (11) about said first hinge axis (AX1) and about said second hinge axis (AX2), said phasing means (30) comprising at least three main arms (31, 32, 33), each for controlling a respective power member (8′, 8″, 8″′) that is connected to a set (6) of swashplates for controlling a rotary wing (2).
