The apparatus comprises a housing (2) and an eccentric rotor (3) having blades (5) slideable in slots (4) to engage the housing (2) to define variable volume chambers. The blades are provided with seal members (6) each having a distal face (61) of a shape complementary to the interior face of the housing (2). The proximal face (60) of the seal member (6) and the distal end of the blade (5) are shaped to permit rocking movement of the seal member with respect to the blade. The apparatus may be an internal combustion engine, a pump, or a compressor. <IMAGE>
