摘要： A volumetric-displacement-maximizing device includes a molded slider (12) bidirectionally movable within an elongate cavity (14) formed within a molded body (16). The body (16) also includes a port structure (18) with an output port (18a) and an input port (18b), each providing channels for communication between the cavity (14) and an extra body location. A power device (22) causes the slider (12) to move bidirectionally within the cavity (14), and the clearance between the slider (12) and the cavity (14) exceeds 0 - but is less than approximately 0.0003 inches. The device of the invention takes several alternative forms including a fluid mechanical device, and has several alternate applications as a pump, valve, or motor. The invention also includes various method features.

摘要： A dual-piston pump apparatus (12) includes a pair of reciprocating sleeves (78) within which a pair of reciprocating pistons (80) are disposed. The pistons (112) and sleeves (78) are each supported on a frame (10) for independent movement along a line angled relative to horizontal by an angle less than about 45 degrees. The apparatus also includes a piston construction including a removable face (112) which permits the piston to be broken down for cleaning. Each piston (80) is normally restricted by a stop from extension beyond the end of the corresponding sleeve, but an actuator is provided for freeing the piston (80) relative to the sleeve (78) so that the piston (80) may be extended beyond the sleeve (78) and the sleeve may be withdrawn from a pump chamber of the apparatus.

摘要： Piston-and-cylinder arrangement (101) has a pressure-balanced piston head (104) mounted on an actuator rod (21). The piston head is mounted for axial movement with the rod, and for radial movement relative thereto. Three annular ring-type seals (118, 119, 120) are provided between facing cylindrical surfaces (115', 112', 112, 115 and 124, 128, 131) of the piston head and rod. The frictional impediment to radial movement of the piston head relative to the rod is minimized, and the improved device exhibits a reduction in the average maximum longitudinal frictional force per stroke.

摘要： The invention consists of multiple diffusers (3) located between the last stage blading of the low pressure turbine (28) and the water columns (7) operating in combination with a counter-current heat exchange (16). The diffusers (3) guarantee the retention of exhaust steam (4) velocity and must be immersed in the condensate water. The compression and condensation of the high velocity exhaust steam (4) from the low pressure turbine (28) is achieved by steam and cold condensate impact with the water columns (7) within the diffusers (3). Two-phase flow assures a higher stagnation pressure which produces increased compression. A counter-current heat exchanger (16) provides the advantage of substantially equalizing the saturation temperature of the low pressure turbine (28) with its inlet cooling water temperature. In addition, for large power stations with two identical low pressure turbines (28), turbine high velocity exhaust steam (4) may be compressed in two stages in order to accomplish double compression.
摘要翻译：本发明由位于低压涡轮机（28）的最后级叶片与与逆流热交换器（16）组合操作的水塔（7）之间的多个扩散器（3）组成。扩散器（3）保证排气蒸汽（4）的流速保持，并且必须浸入冷凝水中。来自低压涡轮机（28）的高速排气（4）的压缩和冷凝通过与扩散器（3）内的水塔（7）的蒸汽和冷凝缩水冲击来实现。两相流动确保较高的停滞压力，从而产生增加的压缩。逆流热交换器（16）提供了基本上使低压涡轮机（28）的饱和温度与入口冷却水温度相等的优点。此外，对于具有两个相同的低压涡轮机（28）的大型发电站，涡轮高速排气（4）可以分两个阶段进行压缩，以实现双重压缩。
