Abstract
An arrangement for the hydraulic adjustment of the propeller blades of an aircraft propeller (1) with the help of a hydraulic pump (5) having a hydraulic cylinder (3) which is acted upon by compressed oil comprises a pressure control valve (11) arranged parallel to the hydraulic pump and connected directly to the pressure connection (4) and intake connection (8) thereof, preferably integrated into the pump housing (14). The pump losses and heating of the oil are therefore reduced and hydraulic efficiency is improved.
