Abstract: A fuel delivery system for automotive engine and like applications which comprises a canister for positioning within a fuel tank having a lower end with a fuel opening and an internal wall spaced from such lower end dividing the canister into upper and lower fuel chambers. An electric-motor fuel pump is positioned within the upper chamber, has a fuel inlet coupled to the lower chamber through the canister wall and a primary outlet for feeding fuel under pressure to an engine. A fluid conduit separate from the pump inlet extends through the upper and lower chamber-separating wall, with an inlet end being positioned within the lower chamber and an outlet end being positioned within the upper chamber. A secondary outlet from the pump supplies fuel under pressure through a nozzle to the fluid conduit for aspirating vapor and fuel through the fluid conduit into the upper chamber. Any vapors entrained in the fuel fed to the upper canister chamber are thus permitted to vent through the canister top.

Abstract: The invention does away with the necessity of moving parts such as a check valve in a nuclear reactor cooling system. Instead, a jet pump, in combination with a TEMP, is employed to assure safe cooling of a nuclear reactor after shutdown. A main flow exists for a reactor coolant. A point of withdrawal is provided for a secondary flow. A TEMP, responsive to the heat from said coolant in the secondary flow path, automatically pumps said withdrawn coolant to a higher pressure and thus higher velocity compared to the main flow. The high velocity coolant is applied as a driver flow for the jet pump which has a main flow chamber located in the main flow circulation pump. Upon nuclear shutdown and loss of power for the main reactor pumping system, the TEMP/jet pump combination continues to boost the coolant flow in the direction it is already circulating.

In use, fluid to be pumped is sucked out of the apertured probe to emerge as fluid bubbles which migrate through the rotating liquid annulus to the liquid-free center, then to pass to the outlet.

Abstract: A rotary compressor comprises a compression chamber defined by enclosing both ends of a cylinder with a main bearing and an end bearing; compression elements including a piston which is eccentrically rotated by a crank shaft within the compression chamber, and dividing the compression chamber into a high pressure chamber and a low pressure chamber; and a sealed container to be a plenum space, in which the compression elements are housed and lubricating oil is sumped at the inner bottom section of the sealed container to effect lubrication of sliding parts of the compression elements, wherein the lubricating oil is returned into the sealed container after it has been cooled through a heat-exchanger provided outside the sealed container.

Abstract: A fluid-driven transducer vacuum tool is disclosed in the preferred embodiment. Pressurized liquid or compressed gas passes through a nozzle tip which is enclosed in a casting. Because the cavities leading to the nozzle tip are of increasingly smaller diameter, a drop in pressure is achieved by the increased velocity of the fluid. Thus, as the fluid leaves the nozzle tip, a vacuum is created which allows substances such as sand or other abrasives, rocks, or slurry to be pulled into the tool through the vacuum inlet. The vacuumed substances pass directly through the apparatus without harming it because the venturi casting of the tool contains a replaceable liner which prevents wear to the tool itself. Because the material can be pulled directly through the tool in this manner, an efficient, portable, and durable tool is provided. As the vacuumed substances are discharged from the apparatus, they can be expelled some distance away from the worksite or transferred to a container.

Abstract: A lateral rotary compressor comprises a compressing mechanism including a blade chamber for filling the lubricating oil, and a blade contained in the blade chamber and reciprocatingly movably between the first position where the blade chamber is increased to the maximum volume and the second position where the blade chamber is decreased to the minimum volume, and a supply tube for communicating the blade chamber with bearings and having an opening formed at the position located in a lubricating oil reservoir.

Abstract: A horizontal type rotary compressor includes a lubricant distribution system which does not require a check valve for preventing the return of lubricant from the frictional bearing surfaces to the blade chamber. An eccentric blade within a blade chamber pumps lubricant out of the blade chamber through an aperture in one wall thereof. A dispensing pipe communicates the aperture of the blade chamber with the frictional bearing surfaces and includes an opening in the pipe adjacent the blade chamber. Reciprocal movement of the blade causes lubricant to be sucked through the aperture of the blade chamber and discharged from the blade chamber into the dispensing pipe. The opening in the pipe permits a larger amount of lubricant to pass into the pipe than out of the pipe, thereby effectively acting as a check valve and negating the need for a separate check valve in the lubricant distribution system.

A level detector in the cylinder controls the oscillation of the system and an accumulator may be provided to smooth the outflow. Substantially continuous flow may be provided by coupling two systems to a common out-feed pipe.
