A rotary piston machine has a housing in which are arranged at least two pistons which are able to revolve together in the housing about an axis of rotation which is fixed with respect to the housing, the pistons being mounted slidingly in a piston cage which is mounted in the housing and revolves together with the pistons about the axis of rotation, the two pistons executing mutually opposing reciprocating motions while revolving about the axis of rotation in order alternately to increase and decrease the volume of a working chamber defined by end faces oriented towards one another of the two pistons and by the piston cage, the axis of rotation passing through the working chamber and the piston cage having a gas exchange opening for admitting and discharging gas to and from the working chamber. The gas exchange opening is arranged on the axis of rotation and a closing member is arranged in the gas exchange opening, which is connected to the piston cage in a rotationally fixed manner with respect to the axis of rotation and is axially movable relative to the piston cage in the direction of the axis of rotation in order to open and close the gas exchange opening, there being present a control mechanism for the closing member which derives the axial motion of the closing member from the rotary motion of the closing member about the axis of rotation.

The invention relates to an oscillating piston engine comprising a housing that contains a first and at least a second piston, both of which can rotate about a fixed rotational axis in the housing and which when rotating about said axis execute counter-rotating displacements back and forth about a pivoting axis that runs perpendicular to the rotational axis through the centre of the housing. A working chamber is situated between opposing end faces of the first and at least second piston. The housing is provided with at least one gas exchange opening for admitting or discharging a gas into or from the working chamber. The pistons are arranged in such a way that the rotational axis runs through the working chamber. The pistons are mounted to slide in a piston cage, which is located in the housing, is concentric with the rotational axis, and rotates together with the pistons about said axis. The gas exchange opening is arranged eccentrically in relation to the rotational axis, on one end face of the housing.

An oscillating-piston machine includes a housing, which has a spherical housing inner wall, at least one piston, which is arranged in the housing and can pivote about a pivot axis passing through the centre of the housing, the at least one piston executing reciprocating pivoting movements when the shaft is rotating, and an at least first surface, which extends radially with respect to the housing inner wall, on a front side of the at least one piston delimiting at least a first working chamber. A rotor element, which is rotationally fixedly connected to the shaft and is arranged outside the centre of the housing, is arranged on a rear side of the at least one piston, the rear side of the at least one piston defining at least one circular running surface, which is not radially oriented, along which the rotor element runs when the shaft is rotating and which forms an angle of ≠90° with the axis of rotation, while the at least one piston does not rotate about the axis of rotation.

An oscillating piston engine comprises a housing in which at least one piston is arranged which can revolve in the housing about an axis of rotation which is fixed in relation to the housing, and which performs when revolving about the axis of rotation reciprocating pivoting movements about pivot axis extending perpendicularly to the axis of rotation between a first end position and a second end position, the at least one piston having a running element which runs, as the piston revolves about the axis of rotation, along at least one control cam which is configured in such a way that the pivoting movements of the at least one piston are derived from the revolving movement of the running element along the control cam. A second running element mounted to the piston and/or a negative-pressure source applying a negative pressure to the backside of the piston are provided for assisting the return of the piston from the first end position to the second end position of the pivoting movement of the piston.

An atomizing nozzle has a flow channel of annular cross section for guiding a medium to be atomized, which flow channel is circumscribed by two walls spaced radially apart from one another and opens into an annular nozzle orifice. Furthermore, a second flow channel for guiding a gaseous spray medium is provided, which flow channel encircles the first flow channel and likewise opens into an annular nozzle orifice. It is proposed that the walls circumscribing the first flow channel are rotatable relative to one another about a nozzle longitudinal axis.
