Abstract
A flow regulator of novel construction is placed across a pump as part of a parallel circuit and enables tapping the principal flow without loss of pumping pressure or introduction of air, subdividing the tapped flow for use in an auxilliary circuit, and/or recombining the flow from an auxilliary circuit with the principal flow. The regulator is formed by a plurality of interconnected passages containing adjustable valve members and separated in part by orifice plates.
Claims4
A flow regulator comprised of a body member, said body member having:
- a. a fluid intake port having a flow regulating valve;
- b. a fluid exhaust port having a flow regulating valve;
- c. a first set of parallel passages interconnected to each other at both ends and in communication with said intake and exhaust ports;
- d. a second set of parallel passages interconnected to each other at both ends, said first set of passages being interconnected with said second set of passages solely at the end of said sets closest to said intake port;
- e. orifice means located in each of the interconnections between said passages of said sets of passages at the end of the passages closest to said intake port, and in the interconnection between said sets of passages;
- f. a first auxilliary port communicating directly with the end of the passages of said second set of parallel passages located closest to said intake port, and having means to restrict the flow therethrough;
- g. a second auxilliary port in direct communication with the other end of the passages of said second set;
- h. a third auxilliary port in direct communication with the end of the passages of said first set located closest to said exhaust port;
- and
- i. valve means in each of said passages of said first and second sets of parallel passages.
