SUBMERSIBLE HYDRAULIC RAM Russian patent published in 1999 - IPC

FIELD: devices for transportation of liquid based on use of hydraulic hammer. SUBSTANCE: supply pipe with impact valve is communicated with delivery pipe by means of delivery valve and with circulating water tank by means of additional delivery valve. Impact valve is made in form of two disks with coinciding water inlet holes which are coaxially mounted on hollow rod provided with slotted guide hole; this rod is placed in supply pipe for performing reciprocating motion. One disk is rigidly secured on rod and other disks is mounted for axial displacement and turn about its axis. Mounted inside rod is steam-pusher provided with head; one end of stem-pusher is spring-loaded on side of rod and is engageable with piston.
