Abstract:
1. An oscillating piston engine, comprising a housing having a center and having an end face, a first and at least a second piston arranged in said housing, said first and at least second piston having mutually facing end surfaces, said first and at least second piston being able to jointly revolve in said housing about an axis of rotation which is fixed in relation to said housing, and to perform, when revolving about said axis of rotation, reciprocating pivoting movements in opposite directions relative to one another about a pivot axis running through said center of said housing perpendicularly to said axis of rotation, a working chamber arranged in said housing between said mutually facing end surfaces of said first and at least second piston, said axis of rotation running through said working chamber, a piston cage arranged in said housing concentrically with said axis of rotation, said first and at least second piston being slidingly mounted in said piston cage, said piston cage being able to rotate together with said first and second piston about said axis of rotation, and at least one gas exchange opening arranged in said housing for admitting or discharging a gas into or from said working chamber, said at least one gas exchange opening being arranged eccentrically with respect to the axis of rotation on said end face of said housing, said axis of rotation running through said end face of said housing, said piston cage having an end face opposing said end face of said housing and having an eccentric opening delimited in direction of revolution about said axis of rotation.
