Fluidomat FNIC are drain nozzle type fluid coupling suitable for Combustion Engine Drive.

The coupling is mounted on engine SAE Flange through stationary housing of coupling and connected to engine flywheel by elastic coupling provided on input shaft of coupling. The output end can be connected suitably to driven machine by a pulley, an elastic coupling or cardon shaft. It has an integrated oil feeding pump driven by the IC engine. A solenoid valve is provided to switch the oil flow either to working circuit or bypass back to oil sump. Oil filter is provided in oil line. Leak off nozzles are provided on coupling periphery. Standard accessories supplied with coupling include oil pump, filter, solenoid valve, flexible coupling on input shaft, oil temperature and pressure switch and oil level indicator.

During Power Transmission (clutching) operation oil flows into working circuit through oil cooler, filter and solenoid valve. Hot oil from working circuits leaks off continuously into oil sump.

The circulating oil after cooler and filter is bypassed back to oil sump without flowing into working circuit. The residual oil in working circuit is emptied by leak off nozzles and the power transmission stops with engine running (Declutching)
