Abstract
Three or more diaphragm pumps (12,14,16) are interconnected to sequentially receive an activation fluid from corresponding piston and cylinder pumps (18,20,22) synchronized by a control mechanism (24) which includes a distributor plate (42) with directive shallow slots (80,82,84) for conduiting activation fluid to a porting plate (44) and via openings (60,62,64) to the piston and cylinder pumps (18,20,22).
Claims7
Apparatus for cyclically and sequentially driving three individual pump diaphragms responsive to a pressurized activation fluid, comprising:
- first, second and third piston and cylinder combinations, each combination having a crankshaft connected for movement with the said piston, and all the crankshafts being interconnected for interactive movement;
- a porting plate fixedly mounted with respect to said combinations and having first, second and third fluid conduits extending therethrough and individually connected to the corresponding combinations;
- a distribution plate having a first major surface in contact with and rotatably mounted with respect to the porting plate and including an opening therein which is aligned during predetermined angular ranges of rotation with each of porting plate conduits;
- and
- a source of pressurized activation fluid in communication with a second major surface of the distribution plate.
