Bypass piston port and methods of manufacturing a bypass piston port for a series progressive divider valve

摘要

A series progressive divider valve comprises a valve body and pistons. A fluid inlet extends into the valve body. Stations are disposed in the valve body and extend from a first end to a second end; each station comprises piston stations extending through the valve body and a bypass station fluidly isolating the first end from the second end. The piston stations comprise a piston bore and a piston. The bypass stations comprise first and second fluid passages extending from the first and second ends to positions inside the valve body. Outlet bores extend into the valve body, and each comprises first and second sets of outlet bores. Porting forms passageways connecting the stations to each other and with the outlet bores such that when high pressure fluid is applied to the inlet the pistons reciprocates from the first end to the second end in sequence.

1. A series progressive divider valve comprising:
a valve body formed of a single block of material, the valve body comprising:
a fluid inlet extending into an exterior of the valve body;a plurality of stations disposed in the valve body and extending from a first end to a second end, the plurality of stations comprising:
a plurality of piston stations extending axially through the valve body from the first end to the second end, each piston station comprising:
a piston bore connecting the first end to the second end; anda piston disposed within the piston bore; andat least one bypass station fluidly isolating the first end from the second end, the bypass station comprising:
a first fluid passage extending from the first end to a first position inside the valve body; anda second fluid passage extending from the second end to a second position inside the valve body; a plurality of outlet bores extending into the valve body, the plurality of outlet bores comprising:
a first set of outlet bores; anda second set of outlet bores; and porting forming a plurality passageways connecting the stations to each other and with the plurality of outlet bores such that when high pressure fluid is applied to the fluid inlet each of the pistons reciprocates from the first end to the second end in sequence.
