    摘要： A vacuum cleaning machine has a cannister with an inlet port and at least two outlet ports. At least two filters are disposed inside of the cannister, one in pneumatic communication through each of the outlet ports. At least two valves are disposed outside of the cannister. Each valve is in pneumatic communication between a vacuum source and an outlet port so as to permit air to be drawn by the vacuum source from the inlet port simultaneously through the filters. A controller operates the valves to switch the filters from the vacuum source to ambient air so as to permit ambient air to be sequentially intermittently drawn through corresponding valves and filters into the cannister. Preferably, the controller includes a timing mechanism for setting the delay time of the sequential valve operation and a timing mechanism for setting the intermittent time of connection of each filter to ambient air.

    摘要： A pair of serially connected electrically operated computer controlled gas valves combine with a pressure sensor to output pressure regulated low pressure gas dispensed from a high pressure gas source and define a pressure regulation system of relatively simple construction, great versatility and of heretofore unknown flexibility, well suited to remote control. The computer controlled valve controller selectively operates the valves in any and all of three operational modes, including the familiar Bang-Bang mode in which both valves operate simultaneously, a Bang-Wait mode in which both valves operate simultaneously for a precise time interval and thereafter close while the outlet gas pressure is checked, and a newly defined Burp mode. In the novel Burp mode, the valve closest to the high pressure gas source is first opened and closed to admit and capture a small volume of gas within inter-valve piping. Thereafter only the outlet valve is opened and closed to release that small volume of captured gas. Each small puff of gas captured and released during repetition of the cycle raises the outlet pressure ever so slightly until the desired pressure is sensed, thereby avoiding significant pressure overshoot.

    摘要： A lubricant fitting (10) adapted to be detachably connected to a valve body (11). The lubricant fitting (10) includes an elongate body (12) that has a central bore (24) therethrough which has an intermediate bore portion (26) that joins opposite inner and outer bore end portions (28 and 30) of an enlarged diameter. Inner and outer annular seats (32 and 34) are formed at the junctures of the intermediate bore portion (26) and the inner and outer bore end portions (28 and 30), respectively. An elongate valve member (50) is mounted within the central bore (24) and has inner and outer valve elements (52 and 54) which have inner and outer shoulders (64 and 86), respectively. The inner and outer annular shoulders (64 and 86) are in opposed facing relationships to the inner and outer annular seats (32 and 34), respectively. A threaded connection (92) exists between the inner and outer valve elements (52 and 54), and allows the inner and outer valve elements (52 and 54) to move longitudinally relative to each other upon the relative rotational movement between themselves to selectively place the inner and outer bore end portions (28 and 30) in fluid isolation so that the lubricant fitting (10) provides an adequate seal between the interior of the valve body (11) and atmosphere at all normal operating pressures within the valve body (11).
