Title:
PISTON BORES AND METHODS OF MANUFACTURING PISTON BORES FOR A SERIES PROGRESSIVE DIVIDER VALVE
Document Type and Number:
WIPO Patent Application WO/2011/149551
Kind Code:
A3
Abstract:
A series progressive divider valve comprises a valve body and pistons. The valve body comprises a fluid inlet, piston bores, outlet bores and porting. The fluid inlet extends into an exterior of the valve body. The piston bores extend through the valve body from a first end to a second end, wherein the piston bores are arranged along a first circular path intersecting each of the piston bores. Each piston bore includes a piston. The outlet bores extend into the valve body, and each outlet bore comprises a first set of outlet bores, and a second set of outlet bores. The porting forms a plurality passageways connecting the piston bores to each other and with the outlet bores such that when high pressure fluid is applied to the inlet each of the pistons reciprocates from the first end to the second end in sequence.
