Abstract: A machine support for a wind power installation, in particular a gearless wind power installation, wherein the machine support is designed to be rotated about a tower axis by means of an azimuth drive, and has a supporting structure which has a first mechanical interface for connecting the machine support indirectly or directly to an azimuth bearing and a second mechanical interface for assembling a generator or an axle journal on the machine support. It is proposed in particular that the supporting structure has one or a plurality of lateral through openings as access to the azimuth drive and/or the azimuth bearing.

Abstract: There is provided a turbine for a hydroelectric power plant comprising a hub, a plurality of turbine blades provided on the hub, a pitch angle adjusting unit coupled to the turbine blades for adjusting the pitch angle of the turbine blades, a double-acting hydraulic cylinder and a piston rod connected thereto. The piston rod is coupled to the pitch angle adjusting unit in such a way that the pitch angle adjusting unit performs a rotational movement when the piston rod is moved in the longitudinal direction. The double-acting hydraulic cylinder is provided in a hydraulic chamber coupled by way of a first and a second hydraulic line so that the double-acting hydraulic cylinder is displaceable by feed of a hydraulic fluid through the first or second hydraulic line and thus leads to adjustment of the pitch angle of the turbine blades by way of the coupling to the piston rod and the pitch angle adjusting unit.
