A sprinkler pressure regulator module has a compact arrangement with a shiftable member having an upper cavity for receiving water flow debris, and a portion of a bypass valve may reciprocate therein. The module includes a stator plate directing water into a drive mechanism, such as a turbine drive mechanism. The shiftable member receives fluid flow from a radially outboard direction and is sealed with a cup portion receiving the shiftable member to define a cup cavity. A module exterior surface is separated from a sprinkler housing to define a vent cavity. A pressure release vent communicates with the cup cavity, a vent channel between the cup portion and the exterior surface, the vent cavity, and the exterior environment. The vent cavity and cup portion provide receptacles for debris deposit. Ribs around an opening of the vent channel with the vent cavity generally prevent debris from entering the vent channel.

Methods and apparatuses for controlling the flow of hydrocarbons from a structure or conduit are provided. An engagement apparatus having a body with threads disposed on an end is lowered into a position suitable for engagement with the structure or conduit, the threads including a deformable material. Rotation of the apparatus to engage the threads with the structure or conduit deforms the material to form a wedge shape that provides a seal between the apparatus and structure or conduit, and resists removal of the apparatus from the structure or conduit. Additional conduits can be secured to the upper end of the apparatus, in combination with a valve. The valve can direct the flow of hydrocarbons from the structure or conduit to selected additional conduits, enabling vessels and/or containers to be removed and/or replaced without wholly ceasing the flow of hydrocarbons in a manner that could cause a buildup of pressure.

System and method for diagnosing faults in vacuum pumps of fuel systems and for diagnosing leaks in fuel systems

Номер: US20120097252A1

Автор: Kurt D. Mc Lain, William R. Cadman

Принадлежит: GM GLOBAL TECHNOLOGY OPERATIONS LLC

A control system includes a switching valve control module, a pressure determination module, and a fuel system diagnostic module. The switching valve control module actuates a switching valve in a fuel system of a vehicle between a first position and a second position, the first position venting a suction side of a vacuum pump in the fuel system to an atmosphere, the second position sealing the suction side of the vacuum pump from the atmosphere. The pressure determination module determines a first pressure on the suction side of the vacuum pump when the switching valve is in the first position, and determines a second pressure on the suction side of the vacuum pump when the switching valve is in the second position. The fuel system diagnostic module selectively diagnoses a fault in the vacuum pump based on the first pressure and the second pressure.

Vibration reducing device for pump cover body of water shut-off diaphragm pump

Номер: US20120097274A1

Автор: Chao Fou Hsu, Ying Lin Cai

Принадлежит: Individual

The present invention provides a vibration reducing device for pump cover body of water shut-off diaphragm pump comprising a hood cover mount and a pump cover body with a containing pit, which orderly accommodates a plastic elastic membrane disk, an obstructing baffle and a compressed spring therein. The plastic elastic membrane disk includes a downward central flow directing buffer, which can insert into a flow directing compartment in the containing pit when the hood cover mount docks with the pump cover body. The flow directing buffer can not only absorb the direct impacting momentum of pumped high pressurized water to the surrounding internal wall of the flow directing compartment but also redirect the random impacting direction of the high pressurized water. Thus, the vibration of the pump cover body with annoying noise created by the impacting momentum of the high pressurized water is deleted.

The insertion opening receives a liquid inlet tube formed in a lid of a waste liquid collection bottle to fit therein, whereby when the liquid inlet tube is fit into the duck-billed tube, the valve opening is compressed to deform and thus open. When the liquid inlet tube is separated from the duck-billed tube, the valve opening is not compressed and thus set in a closed condition.

A split flapper check valve includes one or more additional bushing/bearing surface areas for controlling check valve flapper position along the axis of the hinge pin. This is accomplished by adding one or more grounded bushings between the flappers. The one or more grounded bushings is/are non-rotationally coupled to the hinge pin, and thus grounded to the check valve housing, so that the flappers can bear against this additional surface. The additional bearing area has the effect of increasing the axial bearing surface area according to the number of additional ground lugs that are used, without increasing the diameter of the flapper lugs.

An automated low pressure fluid recovery system is disclosed. An eductor receives low pressure fluid from a source, for example vapors from a hydrocarbon tank. The eductor also receives high pressure fluid from another source, for example the output of a compressor or a well. By venturi principles the two fluid streams are mixed and a third intermediate fluid stream is formed, which is routed to a desired location. The low pressure fluids are thereby beneficially captured and sold or otherwise used. Various sensing devices, such as pressure and temperature sensors, emit signals to a programmable logic controller, which in turn automatically manipulates various control mechanisms to efficiently and safely control fluid flow through the system.
