    • A concentric rotary fluid machine (100) has a first body (102) and a second body (104) that are rotatable relative to each other about a rotation axis (108). The bodies (102, 104) are coaxially arranged one inside the other and form a working chamber (106) there between. A plurality of gates (110) are supported by the second body (104) in respective gate pockets (140). Each gate (110) has a gate cylinder (126) at one end and sealing portion (128) at an opposite end. Each gate pocket (140) has: a gate retention recess (42) which receives a gate cylinder (126); a gate seal recess (144) which receives sealing portion (128); and an intervening land (146). The sealing portion (128) reciprocates up and (10) down within a corresponding gate seal recess and is always in contact with both the recess (144) and the second body (102). A plurality of lobes (112) on the first body cause the gates (110) to swing about respective swing axes (114) as the first body rotates relative to the second body. The lobes (112) and the lands (146) are configured so that a lobe (112) is able to form a substantial seal against a land (146) when in mutual radial alignment.
    • 同心旋转流体机器(100)具有能绕旋转轴线(108)相对于彼此旋转的第一主体(102)和第二主体(104)。 主体(102,104)同心地布置在另一个内部并在其间形成工作室(106)。 多个门(110)由相应的门口(140)中的第二主体(104)支撑。 每个浇口(110)在一端具有一个浇口筒(126),在相对的端部具有密封部分(128)。 每个门槽(140)具有:接纳门柱(126)的门保持凹部(42); 接收密封部分(128)的门密封凹部(144); 和一个中间的土地(146)。 密封部分128在相应的浇口密​​封凹槽内向上和向下往复运动并且总是与凹部(144)和第二主体(102)接触。 当第一主体相对于第二主体旋转时,第一主体上的多个凸角(112)使得浇口(110)围绕相应的摆动轴线(114)摆动。 凸起(112)和凸缘(146)构造成使得当相互径向对准时,凸角(112)能够形成抵靠凸台146的实质密封。
