摘要： A hermetic scroll-type compressor including a housing at discharge pressure, fixed and orbiting scroll members, a frame member having a thrust surface adjacent the orbiting scroll member back surface, and a crankshaft coupled to the orbiting scroll member. A back surface of the orbiting scroll member is exposed to discharge pressure to cause the orbiting scroll member to axially comply with the fixed scroll member. An internal pressure relief valve is connected within the housing to the suction space between the scrolls to compensate for moments of high discharge pressure and relieve orbiting scroll member over loading on the fixed scroll member.

摘要： A counter-rotating machine, such as a positive displacement pump having a pair of meshed, non-contacting helical screws (10,12), subjects its rotating members to axial and radial thrust forces when used for such purposes as compression of liquid or gaseous phase fluids while transporting them through a pump cavity (11,13). Each helical screw (10,12) has a shaft (17,17') which is actively suspended at opposite ends (11a,11b) of the pump cavity by a servo-controlled magnetic bearing assembly (19) and a servo-controlled rotary drive motor (20). Both bearing assemblies and drive motors are mounted on the outside of the pump cavity (11,13). Opto-electric angular position sensors (250) provide synchronization between radial orientation of the drive motors. The bearing assemblies and drive motors conjugately provide axial stabilization and radial centering of the helical screws during volumetric compression of aspirated liquid or gaseous phase fluids.

摘要： The present invention relates to a system (100) for transporting a liquid from a reservoir (600) containing the liquid. The system comprises •a first and second conduit (400, 500), each with a lower end (402, 502) and an upper end (404, 504), •a first pump (200), with an inlet end (201) and an outlet end (202): •wherein one of the lower end (402) of the first conduit (400) or the upper end (504) of the second conduit (500) is connected to a second pump (300): —wherein a height difference between the first and second pump (200, 300) is within a maximum pumping height of a lower pump of the first and second pump (200, 300). Further, the present invention relates to a method for operating a plurality of pumps in a system (100).

摘要： A volatile substance delivery system includes a volatile substance container to contain a volatile substance, an optional absorbent and collapsible element disposed within the container to reduce presence of undesired air during manufacture of the device, an outlet to deliver a volume of the volatile substance from the volatile substance container to an ambient environment, and a manual screw pump to reduce volume (or sometimes, just increase pressure) within the volatile substance container and promote the delivery of the volatile substance from the volatile substance container.
