摘要： A pressure compensation device for use in a high-pressure direct driven pump to control the output pressure of the pump is shown and described. In a preferred embodiment, the high-pressure pump has a valve assembly that selectively allows fluid pressurized by a reciprocating plunger to pass from a pressurization chamber to an outlet chamber from which the pressurized fluid is collected for use. A pressure compensation device has a lever which balances a control force against a force generated by the high-pressure fluid in the outlet chamber. When the outlet pressure exceeds a selected level, the pressure compensation device acts to prevent the further pressurization of fluid by causing the fluid to flow back out of the pressurization chamber via the same passageway(s) through which the fluid was originally introduced into the system.

摘要： An ultra-high pressure hose assembly capable of withstanding sustained internal fluid pressures exceeding 60,000 psi is disclosed herein and consists essentially of an innermost tubular core, a plurality of successive tubular layers and an outer containment sleeve. The innermost tubular core and containment sleeve are designed to add substantially no structural integrity to the overall assembly but rather function only as a fluid barrier and containment structure for the tubular layers respectively. The outer tubular layers serve as structural members of the overall assembly and respectively consist of individual bands which are alternately helically wound around and directly against the layers immediately below them at predetermined helix angles. Each band in turn consists of a number of separate steel wires which have opposing flat sides and which are positioned in unconnected edge to edge relationship to one another so as to form the band. In addition, the bands of successive layers, starting with the innermost tubular layer, define successively increasing helix angles, whereby to cause all of the layers to share substantially in the overall loading of the assembly at its operating pressure.

摘要： An apparatus to remove rubber from airplane tires from an airport runway surface. there is a manifold arm which rotates at as high as two thousand five hundred rpms over the runway surface, with a plurality of water jets being discharged downwardly at a relatively high pressure (e.g. thirty five thousand P.S.I.) against the runway surface. Even though the water pressure is at a level several times higher than that at which damage to the runway surface can occur, at the relatively high linear speed of the water jets (e.g. ninety to one hundred eighty miles per hour), there is no noticeable damage to the runway surface, but yet there is quite effective removal of the accumulated rubber. Also disclosed is a particular shaft and seal assembly which is capable of operating at relatively high rotational speeds and delivering the high pressure to the manifold arm.

摘要： A collision detection sensor for a waterjet system provides a signal in the event the device approaches to within a selected distance of an obstruction in the plane of the working surface. An annular pressure switch lying in a first plane provides the signal when radial pressure is applied to a perimeter of the pressure switch via an annular trigger skirt, the trigger skirt applying the radial pressure in response to a collision of the device with an obstacle.

摘要： A contour follower includes a plurality of sensors spaced around a waterjet nozzle, each of the sensors being configured to measure a distance between a working surface and a first plane, perpendicular to a longitudinal axis of the nozzle. The sensors may include hall-effect sensors lying in the first plane and magnets lying in a second plane, parallel to the working surface. A detecting circuit processes signals from the sensors to determine an angle of the working surface, relative to the first plane, and a distance between an aperture of the nozzle and the working surface. A collision detection sensor provides a signal in the event the device approaches to within a selected distance of an obstruction in the plane of the working surface. A shield plate blocks and dampens secondary spray-back of cutting fluid occurring at low angles above the working surface.

摘要： An improved and tunable ultrahigh-pressure nozzle for use in generating ultrahigh-pressure fluid jets is shown and described. In a preferred embodiment, a nozzle body is provided with a first conical bore that extends from an entrance orifice to an exit orifice, the bore transitioning into a second conical bore that is formed in a seal. The seal is formed to capture a nozzle orifice and position it in the nozzle body adjacent the exit orifice. By selecting the geometry of the nozzle, namely the diameter of the entrance orifice, and an included angle of the first and second conical bores, it is possible to optimize performance of a fluid jet generated by the nozzle for a selected task and operating parameters.

摘要： A high pressure relief valve for use in a high pressure fluid pump is shown and described. In a preferred embodiment, a valve seat is provided with a tapered hole and with a conduit, the tapered hole and conduit being in fluid communication with each other and with fluid having a variable pressure. A tapered pin having grooves is held in the tapered hole by a control force, or control pressure acting through a plunger. When the pressure of the fluid is sufficiently high to overcome the control force or pressure, the tapered pin is forced to move sufficiently to create an annular clearance between the tapered pin and the tapered hole, thereby allowing pressurized fluid to flow past the pin to an outlet. An outer surface of the valve seat in a region of the tapered pin is tapered in an opposite direction to that of the tapered hole, thereby weakening the valve seat in that region, such that the tapered hole is able to expand and contract as the pressure of the fluid increases and decreases.

摘要： A high pressure hose assembly is manufactured wherein the nipple of the hose fitting includes an O-ring receiving groove formed about its periphery. The O-ring and groove are dimensioned so that the crimping of the fitting's outer sleeve causes the linear of the high pressure hose to flow into the groove, comprising the O-ring into the groove, and sealing against the O-ring within the groove.

摘要： A pressure enclosure includes a first component having an opening, a second component coupled to the first component in a position over the opening, a third component positioned between the first and second components and covering the opening, and a load chamber defined by a space between the second and third components and configured such that pressure in the load chamber biases the third component against the first component to seal the opening. The pressure enclosure may be a cylinder of a pump for pressurizing fluid or gas, with the first component a cylinder body, the second component an end cap and the third component a valve body, with the load chamber biasing the valve body against the cylinder body.
