Duplex strainer

摘要

A duplex strainer having a housing with an inlet port and a outlet port. First and second strainer chambers each have first and second ports which are in separate fluid communication with the housing. An efficient scotch yoke design coverts rotation of a first shaft into reciprocal lateral displacement of first and second disk assemblies to permit either the first or second strainer chambers to be closed off to flow while the other of the first and second strainer chambers remain open to flow.
