Abstract: A flow control shuttle to provide the ability to block flow in either direction initially, while allowing a high-pressure differential capacity in one direction and does not produce free floating pieces of the plug in the flow stream after actuation. The mechanism is actuated by a pressure differential opposite the high-pressure direction, in which the actuation pressure can be set independently of the pressure rating of the high-pressure direction. Upon actuation the flow path opens allowing flow in either direction by moving a shuttle plug from a sealed to an unsealed configuration. The direction of high pressure and actuation pressure can be chosen by direction of installation on based what is required for the application. This mechanism can be incorporated into an existing tool or a new tool design, or can be provided as a standalone tool.

Abstract: A pumping system includes a chamber (10) having an intake orifice (11) for introducing liquid into said chamber (10). A discharge orifice (12) discharges the liquid from the chamber (10). Another orifice (13) receives pressurized gas. A valve is located at each of the orifices (11, 12, 13). The valves (15, 16, 17) are controlled in synchronization according to two phases.

Abstract: A core-material container constituted of a container main body whose opening is covered with a sheet-like lid member made of an air-permeable material. In order to charge powder core material through a core-material charging inlet uniformly as well as densely, the charging operation of the core material is carried out in the following manner: housing the core material container in a housing space formed by a positioning guide and a plate member; releasing air from a suction outlet, thereby making the core-material charging inlet adhere around a nozzle; releasing air located inside a sealed space enclosed by an upper frame and a lower frame through an air outlet; and charging the core material through the nozzle while evacuating the core material container. Thus, the core material is uniformly charged by air flows caused by the air release, and the charge is densely carried out since air contained in the core material is removed.
