Abstract: A wind turbine blade with a flow guiding device attached to a profiled contour on a pressure side of the blade is described. The flow guiding device extends along at least a longitudinal part of a transition region of the blade and is arranged so as to generate a separation of airflow along at least a central longitudinal portion of the flow guiding device from the pressure side of the blade at a point between the flow guiding device and a trailing edge of the blade, when the blade is impacted by an incident airflow. The inflow surface, in at least the central longitudinal portion, is formed so that, for each transverse cross-section, a end point tangent to the inflow surface at the end point crosses the profiled contour at a crossing point, where the profiled contour has a profile tangent to the profiled contour, and wherein an angle between the profile tangent and the end point tangent is at least 45 degrees.

Abstract: The invention concerns a linear compressor (1) with a piston (16) reciprocating in a cylinder (8), a linear motor acting upon the piston (16) and a resonance spring arrangement (5) connected with the piston (16). It is endeavoured to reliably avoid damaging the compressor during operation. For this purpose, the resonance spring arrangement (5) has a fixed stop (48) allocated to the upper dead point of the piston (16).

Abstract: The invention concerns a linear compressor (1), particularly a refrigerant compressor, with a linear motor (4), which comprises an outer stator (18), an inner stator (20) and an armature (22) located in a gap (21) between outer stator (18) and inner stator (20), and a compression unit (3), which has a cylinder (8) and a piston (16) reciprocating in the cylinder (8) and being connected to the armature (22). It is endeavoured to simplify the design of the compressor. For this purpose, the inner stator (20) and the outer stator (18) are held and positioned in relation to each other at both axial ends by means of motor covers (29).
