Abstract:
1. An oscillating piston machine, comprising: a housing; a first and a second piston arranged in said housing, said first piston having a first end face and said second piston having a second end face facing said first end face, a rotational axis fixed with respect to said housing, about which said first piston and said second piston can rotate together in said housing, said pistons, when rotating about said rotational axis, carrying out reciprocating oscillating movements in opposite directions to one another about an oscillation axis which extends perpendicular to said rotational axis, a working chamber bound by said first end face and said second end face, said first piston and said second piston being arranged such that said rotational axis extends through said working chamber; wherein a third piston and a fourth piston are further arranged in said housing, said third piston and said fourth piston rotating with said first piston and said second piston about said rotational axis, said third piston and said fourth piston defining a second working chamber; wherein said first piston, said second piston, said third piston and said fourth piston are arranged with respect to said rotational axis in such a way that said oscillating movements of said first and second pistons occur in a first plane, and said oscillating movements of said third and fourth pistons occur in a second plane; wherein said first and second planes are rotated relative to one another by an angle which is unequal to 0° with respect to said rotational axis.
