Free flow breaker switch - has two opposing spaced orifices with a sensor channel connected to a flow intensifier

摘要

Flow medium operated free-flow breaker switch of simplified construction with coaxially opposite, spaced orifices, within a free sensor gap, where the main orifice is directly connected to a hydraulic supply through a main channel and the other, approach flow channel, is connected to the same supply via a branch channel including a choke. There is a sensor channel connected with flow intensifier, connected to the other orifice behind the choke. This sensor channel deflects from the branch channel at a given position near the choke outlet. A choke body is inserted in the branch channel and its position is adjustable with respect to the branching point of the sensor channel from the branch channel.
