摘要： The present invention concerns a pump that includes a drain path for a liquid and a drain unit configured to realize the suction of the liquid along the path. In accordance with the invention, the pump further comprises a containment chamber to contain the drained liquid, and one or more than one exiting conduits in fluid communication with the containment chamber. Moreover, one or more than one vertical conduits are provided that develop from the containment chamber upwards and in fluid communication with the containment chamber. In such a manner, the vertical conduits form with the exiting conduits, through the containment chamber, one or more than one vessels communicating one with the other in such a way that the liquid that is drained by the drain unit into the containment chamber re-ascends along the exiting conduits towards the level of liquid contained in the vertical conduits.

摘要： An airflow passage structure of manual pump of fluid-pumping apparatus includes a first control valve and a second control valve. The first and second control valves are movable between different positions to change flowing path of air so as to increase or decrease the air pressure in the chamber of a container of the fluid-pumping apparatus. In a relief operation mode, the air in the chamber is guided to go into a first compartment of the interior space of the manual pump and then go into a second compartment thereof to be exhausted into the atmosphere. On the other hand, in a pressurization operation mode, the communication between the chamber and the first compartment is interrupted and the air goes into the second compartment and then is pressurized and filled into the chamber to increase the pressure in the chamber.

摘要： A pump for transferring particulate material from a source to a remote location, including a particulate chamber having open ends, check valves at the open ends, a vacuum source connected to the chamber adjacent one end, a gas source at the opposed end of the chamber and a control which alternatively connects the vacuum to the chamber to draw particulate material from the source to the chamber and connecting the gas under pressure to drive the particulate material to the remote location. In a preferred embodiment, the chamber has a cylindrical inner diameter and the source of vacuum is a venturi pump connected to a pinch valve permitting overflow of particulate material through the pinch valve and venturi pump, which is returned to the source. In one embodiment, the pinch valve surrounds an open end of the chamber permitting overflow while avoiding agglomeration of the particulate material.

摘要： An improved bulk fluid distribution for supplying process fluids to semiconductor process tools. The improved system having an alternating pressure vessel engine substantially eliminates pressure fluctuations in the bulk fluid supply line due to head losses from the changing weight of the fluid in the dispensing vessels. The system also enables flexible control of the flow conditions of the fluid in the fluid supply line.

摘要： A gas pressure driven fluid pump having a pump tank with a liquid inlet and a liquid outlet. A float assembly is carried within the interior of the pump tank and is movable between a low level position and a high level position. A compression spring is connected between the float assembly and a pivot member. Due to the force applied by the compression spring, the pivot member rotates to a first position when the float reaches its high level position and rotates to a second position when the float reaches its low level position. A valve assembly is connected to said pivot member to switch between motive porting and exhaust porting in a snap over fashion due to rotation of said pivot member between said first position and said second position. A damper system may be connected to the valve assembly to slow movement of the valve assembly between motive porting and exhaust porting.

摘要： A gas pressure driven fluid pump having an electronic cycle counter. The pump has a pump tank with a liquid inlet and a liquid outlet. A switching mechanism is operative within the pump tank for switching to exhaust porting when the fluid level within the pump tank falls to a low level position and switching to motive porting when the fluid level within the pump tank rises to a high level position. An electrical counter circuit is operatively connected to the pump tank for incrementing a stored count in response to the fluid level within the pump tank rising to a predetermined level.

摘要： A hydropower conversion system is provided which uses a hydraulic gradient to accelerate water in a drive pipe. A valve is disposed in drive pipe to interrupt the flow of water and thus create a temporary negative pressure within the drive pipe. A negative pressure relief device with a riser section is coupled to the drive pipe and is adapted to pull air but not water into the riser section when under negative pressure. A pneumatic device such as a power turbine is coupled to the negative pressure relief device.
