ABSTRACT:
A hydraulic circuit includes a fluid pressure inlet line (1); a fluid pressure delivery line (2); and a filter unit (FU) interposed between the inlet line (1) and the delivery line (2), with the circuit incorporating an automatic back flushing facility. The latter comprises a valve arrangement A, B, C, D, capable of temporarily preventing initial flow of fluid through the filter unit (FU) in a delivery direction, causing reverse fluid flow through the filter unit (FU) in a back flushing direction, for a predetermined period, with the flushing sequence initiated by the valve arrangement sensing a flow of fluid, at a predetermined pressure, and after the predetermined period, causing fluid flow in the normal delivery direction.
