Abstract
Apparatus is provided for detecting leakages in hydraulic equipment. A pressure supply line of the equipment has alternate fluid flow paths controlled by respective, oppositely directed non-return or one-way valves which are pre-loaded as by springs. A restricted flow transducer is located in a bypass line which bypasses the alternate fluid flow paths for sensing pressure drops in the system.
