Abstract
An oscillating piston machine comprises a plurality of pistons which are arranged in a housing, rotate together in the housing about an axis of rotation which is essentially central in the housing and is fixed to the housing, and execute reciprocating oscillating movements about a respective oscillation axis as they rotate in the housing, in each case two adjacent pistons executing oscillating movements in opposite directions. The housing is of spherical construction on the inside, the oscillation axes of the pistons being formed by a common oscillation axis which run essentially through the center of the housing.
