Abstract: The high pressure system 10 is provided for outputting pressurized fluid to a source, such as a blasting gun 26. The system includes mechanical transmission 14 interconnecting a diesel engine 12 with a positive displacement pump 20. A programmable controller 30 is provided for receiving signals from a pressure transducer 34 and for controlling operation of an engine controller 44, a clutch controller 42, and a transmission shifter 46 to obtain the desired fluid pressure level output from the pump. The controller preferably communicates by wireless transmission technology, so that the controller 30 may be exterior of a sound abatement enclosure 28 surrounding the engine 12 and the transmission 14. Controller 30 may be operated to automatically shift the transmission in response to fluid pressure output from the pump. Alternatively, controller 30 may receive input instructions from the operator to shift the transmission to a desired gear.

Abstract: The present invention relates generally to a non-clogging slurry nozzle apparatus and method for avoiding blockages in slurry nozzles associated with the jetting of mixtures of soluble and/or insoluble abrasives and high pressure fluids. The apparatus involves the use of a pressure actuator which opens and closes gates of a valve, permitting a compressed gas to enter the nozzle and remove all abrasive material from a nozzle when jetting is interrupted, thus preventing the abrasive material to remain in the nozzle where it may adhere with residual moisture and form blockages. The present invention lessens the opportunity for abrasive material blockages in slurry nozzles and improves the efficiency of cleaning operations by reducing the need to interrupt blasting operations to remove abrasive blockages from the slurry nozzle.

Abstract: Nozzle-effect well apparatuses including nozzle-effect protectors, centralizers and stabilizers and related methods, the apparatuses having two or more blades or ribs extending outwardly from a body, the blades or ribs spaced apart further at one end of the apparatus than the other; in one embodiment, the wall thickness of the apparatus varying so that one end is thicker than the other or a portion or portions between the ends are thicker or thinner in wall thickness than other portions; in another embodiment, portions of valley areas between ribs or blades varying in size to create nozzle effects.

Abstract: A sandblasting device comprises a first and a second conduit, generally parallel, which are used for the conveyance of a pressurized fluid and of sand respectively.Their outlet ends are connected to a terminal support on which is mounted a removable and orientable nozzle. This nozzle is structured and positioned in such a way as to direct the sand, through a fan-shaped jet of the pressurized fluid coming from the first conduit, on to the surface to be cleaned. The sand stream coming out of the second conduit assumes a transverse lenticular cross-section.

Abstract: A liquid blasting system for blasting an area, surface, structure, part, item, or member with liquid or with liquid and abrasives, or with a liquid-abrasive mixture. The system has a housing through which are disposed a plurality of inlets or nozzles. Liquid, e.g. water, under pressure is transmitted through the inlets or nozzles to the area, etc. to be blasted. Abrasives, e.g. sand, may be injected with the liquid or separate abrasive injection inlets or nozzles may be employed in connection with the liquid inlets or nozzles. The inlet or nozzle housing can communicate with a collection housing for receiving blasted material, liquid, and abrasives and the collection housing can have ports therein through which these liquids and materials can exit. The ports can be suitable for connecting thereto a vacuum source for sucking materials and liquid from the nozzle housing, to and through the collection housing, and thence out of the collection housing.

Abstract: A multiple high pressure liquid nozzled gun system and flow controller therefor. The flow controller permits the connection of two guns and allows activation or de-activation of one gun without affecting the other gun. The flow controller has multiple internal channels which re-direct liquid flow upon activation or de-activation of a gun. The flow controller has high pressure channels through which liquid under high pressure flows to the gun nozzles and alternate channels through which liquid may flow when the guns are in a trigger-released or "dump" mode permitting liquid to flow through the controller, to the gun, and out of the gun's dump port.

Abstract: A pump and a stress and fatigue resistant pump head, one embodiment of which is useful for a high pressure pump and having a manifold, a valve cartridge, inlet and outlet valves in the valve cartridge, a pump fluid cylinder with a reciprocating plunger therein, a packing cartridge with packing for the plunger. The pump head may exhibit one or more of the following features: a. increased diameter packing cartridge; b. increased length front bushing; c. inclined inlet valve; d. inlet valve spring in valve cartridge on manifold side of valve; e. decreased diameter of high pressure seal of packing cartridge.

Abstract: A fluid spray apparatus for oscillating a fluid discharge head attached thereto and a self-oscillation apparatus. The fluid spary apparatus may have a mounting for receiving and holding a fluid discharge device or devices, the mounting member being pivotably connected to dual supports which are in turn movably mounted on a body member with a lost motion means so that a component of the force reacting to the fluid discharge effects oscillating movement of the fluid spray device.
