<p>PURPOSE:To improve workability be arranging machining bores, fluid intake ports, discharge ports of a pump chamber, etc. on either surface except two surfaces opposite to a casing formed respectively into hexahedron. CONSTITUTION:A casing 1 is formed into hexahedron, each machining bore, fluid intake port, fluid discharge port of a pump chamber 5, a strainer chamber 14, a filter chamber 20 and an air separator chamber 30 are installed on either surface except two surfaces opposite to the casing, so that when machining the casing, it is achieved by performing tetrahedral machining in the condition that two surfaces opposite to the casing are set to be chucked. In consequence, productive efficiency is remarkably improved with omitting pieces of odd jobs, such as disassembling and displacing the casing during the machining.</p> |
