摘要： An illustrative embodiment of the present disclosure includes a pump having a rotor and a plurality of vanes. The rotor is attached to a motor that rotates it in first and second directions and is located in a cavity. The plurality of vanes are each pivotally coupled to the rotor so as the rotor rotates, the vanes selectively push fluid from an inlet port out through an outlet port. The plurality of vanes each have an end selected from the group consisting of a lobe, no lobe, and a rod located in the lobe. Each of the plurality of vanes also includes a pivot pin configured to fit in a corresponding receptacle located in the rotor so that each of the plurality of vanes is pivotable with respect to the rotor inside the cavity.

摘要： A roots-style blower (210) has a housing (214), rotors (230) and manifolds (212) for the housing (214). The housing (214) forms an inlet plenum (220), a rotor chamber (224) and a discharge plenum (228). The rotors (230) have straight lobes (232) spaced by pockets (240). The pocket (240X) that traps gas between a leading and following lobe (232) and an inside wall of the rotor chamber (224) is a temporary closed cell (240X). The manifolds (212) and the housing (214) form a pair of back-pass loops (250-251), one for each rotor (230). Each back-pass loop (250-252) comprises a back-pass chamber (250), outer channels (252) from the discharge plenum (228) to the back-pass chamber (250), and inner channels (251) to the rotor chamber (224). Wherein, the back-pass chamber (250) volume as a percentage of closed cell (240X) volume ranges between about fifty-six percent (56%) and one-hundred-seventeen percent (117%).

摘要： An inductor or eductor that includes two or more tanks or receptacles that have different volumetric sizes and correspondingly proportional graduate scales by which different incremental volumes of fluids, dry powders, granular materials, etc. can be accurately measured therein. The outlets of the tanks or receptacles are plumbed together so that material in each can be simultaneously evacuated out and into a fluid supply line. Use of the inductor or eductor together with one-way, dry-disconnect valves provides a closed system by which materials such as agricultural chemicals can be accurately, measured, dispensed and transferred.

摘要： A positive displacement pump (12) includes a rotor (50) having a front face (62) and a rear face (54) positioned in the fluid chamber (22). Each of the faces of the rotor is spaced apart from a corresponding inner wall (28,26) of the fluid chamber (22) to define predetermined clearances therebetween. A shaft (44) is connected at a first end to the rotor to effect rotation thereof and extends through a bore (40) in the housing. A thrust bearing assembly (100) includes an adjusting collar (102) and a thrust bushing (110). The adjusting collar (102) is attachable to the shaft and includes a central bore through which the shaft extends. The thrust bushing (110) is secured within the bore of the housing by a locking ring that prevents longitudinal movement of the thrust bushing toward the fluid chamber. The adjusting collar (102) is rotatable with the shaft and is in relative rotatable engagement with the thrust bushing. The adjusting collar and the thrust bushing prevent movement of the shaft and the rotor in a direction away from the adjusting sleeve and toward the rear inner wall of the fluid chamber (22) such that the predetermined clearances between the faces (54, 62) of the rotor and the internal walls (26,28) of the housing are substantially uniformly maintained as the rotor rotates.

摘要： A double diaphragm pump is provided. The pump includes an inlet manifold, an outlet manifold, an air valve housing, first and second diaphragm housings, and a collar. The inlet manifold has at least one passageway configured to direct fluid from an inlet port on the inlet manifold. The outlet manifold has at least one passageway configured to direct fluid to an outlet port on the outlet manifold. Each of the housings is in selective fluid communication with the inlet and outlet manifolds. The collar is configured to be rotatably attached to the inlet manifold and the pump.
