1. A Driving system (13) comprising a housing (10) having a spherical hollow space (11), a rotatable main shaft (14), a driving means (16) drivingly connected to the main shaft (14) and a piston construction (15) connected to the driving means (16), where the piston construction (15) is rockable backwards and forwards in the hollow space (11) relative to a stationary wall portion (12) in the hollow space (11) and where one end of the driving means (16), which participates in the rotational motion of the main shaft (14) is pivotally mounted in the main shaft (14) about a pivotal axis (16b) which forms an acute angle with the rotational axis (14a) of the main shaft (14), characterized in thatthe piston construction (15), which comprises a pair of mutually rigidly connected pistons (15c,15d), is rockable relative to the surrounding housing (10)about a first rocking axis (15a), which centrally passes through the spherical hollow space (11) at right angles to the rotational axis (14a) of the main shaft (14), that the piston construction (15) is rockable towards and from an intermediate, stationary wall portion (12), which projects radially inwards into a first hollow space section (11a) of the spherical hollow space (11) and divides the hollow space section (11a) into two opposite work chambers (11a

    ), that the other end of the driving means (16) is rockably mounted in the piston construction (15) about a second rocking axis (16a), which extends at right angles to the first rocking axis (15a), the first and second rocking axes (15a,16a) crossing the rotational axis (14a) of the main shaft (14) at a common crossing point (11c) centrally in the spherical hollow space (11).
