A hydrocyclic motor which is useful as a pump or as an hydraulic or pneumatic engine with a high torque low speed output. The hydrocyclic motor (10) comprises at least one cycloid disc (24) having a generally curved outer surface (42), at least one reciprocably mounted piston (26), the outer curved surface of the cycloid disc (24) being formed of alternating crests (44) and valleys (46) and there being provided a plurality of rollers (48) which are aranged to engage with the curved surface (42) of the cycloid disc (24), the number of rollers (48) and the number of crests (44) being different by at least one. Feeding fluid to the piston (26) causes the piston (26) to reciprocate so that the cycloid disc (24) is caused to undergo orbital movement and the housing (12) is thus caused to rotate. |
