Definitions
- This invention relates to material pumps. It is disclosed in the context of a pump for pumping, for example, coating material (hereinafter sometimes paint), but is believed to be useful in other applications as well.
- coating material hereinafter sometimes paint
- an assembly of multiple fluid pumps is provided.
- Each pump includes a movable component.
- a crank is coupled to the movable component. At least two of the movable components define between them a non-zero included angle.
- the crank comprises at least two throws, the apparatus further including at least two connecting rods, the crank being coupled to the movable components by the at least two throws and the at least two connecting rods.
- the at least two throws comprise at least three throws, one of the at least three throws defining substantially equal included angles with the other two of the at least three throws.
- the at least three throws comprise n throws, n an integer greater than 2, each throw making included angles with two others of the n throws, each said included angle being about 360 n.
- an assembly of multiple fluid pumps is provided.
- Each pump includes a movable component.
- a cam is coupled to the movable component.
- At least two of the movable components define between them a non-zero included angle.
- the assembly further includes at least two followers. The cam is coupled to the movable component by the at least two followers.
- the cam is configured to drive at least two of the pumps such that one of the at least two pumps reaches the beginning of an exhaust stroke at substantially the same time that the other of the at least two pumps reaches the beginning of a priming stroke.
- the apparatus comprises m cams, m an integer greater than or equal to 2, each cam including p lobes, p an integer greater than or equal to 2, a line drawn between peaks of two adjacent lobes of one of the m cams making non-zero angles with lines drawn between peaks of any two adjacent lobes of another of the m cams.
- the pumps are coating material pumps.
- Fig. 1 illustrates a fragmentary, partly sectional side elevational view of a composite pump constructed according to the invention
- Fig. 2 illustrates a fragmentary sectional view of the embodiment illustrated in Fig. 1, taken generally along section lines 2-2 thereof
- Fig. 3 illustrates a partly broken away top plan view of a composite pump constructed according to the invention.
- a composite pump 120 includes multiple fluid pump sections 120-1, 120-2, . . . 120-n, only one of which is illustrated. Typically, the components of the composite pump are supported in a frame 121. Each pump section
- 120-1, 120-2, . . . 120-n includes an operating rod 122-1, 122-2, . . . 122-n, respectively.
- the pump 120 further includes a crankshaft 124 rotatably mounted in suitable bearings.
- Crankshaft 124 has throws 124-1, 124-2, . . . 124-n.
- Operating rods 122-1, 122-2, . . . 122-n of pump sections 120-1, 120-2, . . . 120-n, respectively, are coupled by connecting rods 126-1, 126-2, . . . 126-n, respectively, to throws 124-1, 124-2, . . . 124-n, respectively.
- the throws 124-1, 124-2 When viewed from an end 128 of crankshaft 124, the throws 124-1, 124-2,
- throw 124-1 need not be offset by equal angles between throw 124-2 and 124-n. Indeed, throw 124-m and throw 124-(m - 1) or 124-(m
- throw 124-m lies at equal angles between some two of the remaining throws 124-1, 124-2, . . . 124-(m - 1), 124-(m + 1), . . . 124-n. It should further be understood that it is not necessary for throws to be offset at equal angles from each other.
- the invention may be practiced using a crankshaft having only two throws which are angularly offset from each other by, for example, 90°.
- the pistons of pump sections 120-1, 120-2, . . . 120-n are driven out of phase to provide a supply of the fluid which has reduced pumping pressure pulses.
- a composite pump 220 constructed according to the invention includes multiple fluid pump sections 220-1, 220-2, . . . 220-n supported in a frame 221.
- Each pump section 220-1, 220-2, . . . 220-n includes an operating rod 222-1, 222-2, . . . 222-n, respectively.
- the pump 220 further includes a crankshaft 224 rotating one or more suitably shaped, for example, somewhat elliptical or cardioid shaped, cams 226-a, 226-b, . . . 226-m.
- a follower 228-1, 228-2, . . . 228-n is coupled to each respective operating rod 222-1, 222-2, . . . 222-n.
- 228-n are coupled to each other in opposed pairs, 228-1, 228-2; 228-3, 228-4; . . . 228-(n - 1), 228-n by coil tension springs 230, so that they are continually urged against camming surfaces 232 of respective cams 226-a, 226-b, . . . 226-m.
- the other of the respective opposed sections 228-2; 228-4; . . . 228-n reaches the beginning of its pumping stroke, thereby smoothing the flow of the pumped fluid.
- cams 226-a, 226-b, . . . 226-m may also be oriented with their lobes at non-zero angles to each other.
- the cams 226-a, 226-b, . . . 226-m are somewhat elliptical, having lobes at the two opposite ends of their major axes, the major axes of the cams 226-a, 226-b, . . .
- 226-m may be oriented at non-zero angles to each other so that the pumping and priming strokes of each opposed pair 220-1, 220-2; 220-3, 220-4; . . . 220-(n - 1), 220-n of pump sections are out of phase with those of the other opposed pairs 220-1, 220-2; 220-3, 220- 4; . . . 220-(n - 1), 220-n of pump sections.
- This arrangement further smooths the flow of the pumped fluid.
