A fluid machine for a pneumatic or hydraulic drive system, said fluid machine being able to work as a fluid motor or as a fluid pump, comprising: at least two piston assemblies each comprising a piston means (110a-c), the at least two piston assemblies being operable to cause sequential reciprocating movement of the pistons means (110a-c); a drive member (120) rotatable about an axis and providing an annular, wave-like surface (122) extending at least partially radially to the axis, towards which the piston means (110a-c) project, wherein, in case of working as a fluid motor, the pistons means (110a-c) are arranged to drive rotation of the drive member (120) about the axis at least by a pushing action on said wave-like surface (122) or, in the case of working as a fluid pump, the piston means (110a-c) are arranged to cooperate with said wave-like surface (122) so that rotation of the drive member (120) drives sequential reciprocating motion of the piston means (110a-c).
