A fluid handling device which when suitably configured can be used as a pump, compressor or as a rotary engine. In the illustrated application, there are three primary active components. These are two identical rotating segments or pistons and a centrally disposed rotating disk that forms chambers of variable volume with the rotating segments or pistons. The disk member carries a spherical chamber open at diametrically opposed locations to receive a pair of rotating shafts which carry the rotating segments or pistons. This spherical chamber forms a seal with complementary spherical surfaces on the rotary piston members. The disk member is journalled in two sets of bearings carried by yoke members one of which is carried by each rotating shaft.
