Abstract
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.
