摘要： A control valve assembly including a water meter usage assembly including discs which are relatively positionable to adjust the frequency at which regeneration in a water treatment system starts. A regeneration control disc mounted coaxially with the meter disc assembly includes structure for releasing a drive mechanism associated with the meter disc assembly to rotate it back to a start position under a predetermined operating condition. The discs are releasably held in their relative positions by at least one pawl and at least one of the discs is rotatable relative to the other disc. The regeneration frequency is determined by an initiation slot in one of the discs and its operative position is determined by disc positions. The regeneration control disc is rotated by a pawl mechanism that is activated when an associated cam follower is received by the regeneration initiation slot formed in the water meter usage assembly.

摘要： This invention relates to a device for automatically switching discharge of pressurized fluid from outlet ports. To be more specific, this invention relates to an automatic pressurized fluid switching device for performing a switching operation using the pressure of pressurized fluid in itself without using electrical elements. An object of the invention is to provide an automatic pressurized fluid switching device having an excellent switching performance without using an electrical element so as not to be complicated in structure. To attain the object according to the invention, there is provided an automatic pressurized fluid switching device comprising an inlet port for introducing pressurized fluid, a plurality of outlet ports for discharging the pressurized fluid, a switching valve disposed between the inlet port and the outlet ports for switching over the outlet ports, a pilot valve for piloting the switching operation of the switching valve, and a reaction member for controlling the pilot action of the pilot valve in response to the pressure of the pressurized fluid introduced, which is characterized in that the pilot valve is provided with a first pilot unit in which the pilot action of the pilot valve is controlled only by the reaction member, and a second pilot unit in which the pilot action of the pilot valve is controlled by the reaction member in its initial and final stages and directly by the pressurized fluid in its middle stage. According to the invention, two lineages of the pilot action of the pilot valve for piloting the switching action of the switching valve can be constituted. The lineages are formed of the pilot action controlled only by the reaction member in the first pilot unit and the pilot action controlled by both of the reaction member and the fluid in the second pilot unit. The pilot action in the second pilot unit is controlled by the reaction member in the initial and final stages and by the pressurized fluid in the middle stage. Consequently, the pilot action in the second pilot unit in the middle stage can be securely effected even when the pressurized fluid introduced thereinto is little at the time of being again operated after stopping at the intermediate point of the switching action. Thus, smooth switching action can be performed securely.

摘要： A fluid pressure amplifier comprises a pipe for flowing fluid and having an array of holes formed therein through which fluid can flow from within the pipe in use and resiliently-movable obturator means adjacent the pipe and operatively responsive to fluid inlet pressure in the pipe, in which fluid inlet pressure causes the obturator means to oscillate between conditions which alternately permit and prevent fluid from passing through the holes, whereby the fluid leaving the pipe has a pulsed increased pressure. The amplifier is intended for use especially to increase the pressure of water flowing through a pipe submerged in a river, to provide a pumping action to a higher level.

摘要： A pool sweep (1) having a continuously-cycling, flow-interrupting valve (8) at the upstream entrance to an inertial flow chamber (7). The valve (8) has an entrance mouth with one or more closure lips (17) pivoting between open and closed positions to open and close the mouth. The lips (17) are biased towards the opened position with low creep biasing means, as by materials having a strain at their elastic limit of below 0.5 such as one or more metal springs (37) urging the lip toward closure. Desirably, the opening bias is substantially less than the closing force on the lips (17) created by the water flow under steady flow conditions as well as over an opening-initiating region towards the open position beginning from the full closure and in the region intermediate these two end regions.

摘要： Systèmes de distribution pulsée de fluide d'irrigation, comprenant un réservoir de tête (12) alimentant au moins une ligne d'irrigation (33) dans laquelle se trouve un réseau de vannes émettrices (35, 36, 70, 76) reliées en série au réservoir de tête (12). Des tuyaux élastiques (37, 40) situés entre les vannes émettrices (35, 36, 70, 76) servent de réservoirs pour le fluide d'irrigation entre les impulsions. Un générateur d'impulsions (13) relie la canalisation (10) de fluide d'irrigation au réservoir de tête (12) lorsqu'il est actionné par une vanne pilote (53). Un soufflet accumulateur (25) est éventuellement relié au réservoir de tête (12) pour recueillir l'excédent de fluide et le réintroduire dans le système à un moment approprié au cours du cycle d'impulsions. Par ailleurs, la vanne pilote (53) répond aux variations de pression en actionnant et en arrêtant le générateur d'impulsions (13). Une chambre à capacité variable (97) chargée élastiquement de manière réglable, ainsi qu'une diode fluidique (90), sont couplées à la vanne pilote (53) et s'associent l'une à l'autre pour déterminer la fréquence de répétition des impulsions d'irrigation.
