Device for building up high pulse liquid pressures

Claim 1

A DEVICE FOR BUILDING UP HIGH PRESSURE PULSES OF LIQUID, COMPRISING AT LEAST ONE CYLINDER AND ONE PISTON HOUSED IN SAID CYLINDER; SAID CYLINDER HAVING AT ONE SIDE OF THE PISTON A FIRST SPACE CONNECTED THROUGH AN OPENING IN THE CYLINDER WITH AT LEAST ONE RECEIVER FILLED WITH COMPRESSED GAS AND SERVING AS A LOW-PRESSURE CHAMBER; SAID CYLINDER HAVING AT THE OTHER SIDE OF THE PISTON A SECOND SPACE IN THE BODY OF THE CYLINDER FACE PORTION, FILLED UP WITH LIQUID AND PROVIDED WITH AT LEAST ONE OUTLET OPENING; SAID SECOND SPACE HAVING A CROSS-SECTION CORRESPONDING TO THE CROSS-SECTION OF THE PISTON AND SERVING AS A HIGH PRESSURE CHAMBER, SAID HIGH PRESSURE BEING BUILT UP AS A RESULT OF THE IMPACT OF SAID PISTON UPON THE LIQUID, SAID PISTON INCLUDING IN THE FACE PORTION AT THE SIDE OF THE HIGH PRESSURE CHAMBER A TAPER-SHAPED LUG; CIRCULAR GROVES BEING PROVIDED ON THE EXTERNAL SURFACE OF THE PISTON PORTION ENTERING THE HIGH-PRESSURE CHAMBER; AN ANGULAR THROUGH CHANNEL BEING PROVIDED IN SAID PISTON AND CONNECTING ITS SIDE SURFACE WIOTH THE FACE SURFACE AT THE SIDE OF THE LOW PRESSURE CHAMBER; A NON-RETURN VALVE WITH A THROUGH OPENING BEING PROVIDED IN THE PLUNGER OF SAID NON-RETURN VALVE LOCATED IN SAID ANGULAR CHANNEL; SAID CYLINDER HAVING IN THE SIDE WALL OF THE HIGH PRESSURE CHAMBER AT LEAST ONE OPENING FOR DELIVERING THE LIQUID UNDER PRESSURE FOR FORCED TRAVEL OF SAID PISTON IN THE DIRECTION OF THE LOW-PRESSURE CHAMBER, OPENINGS SERVING FOR THE DISCHANGE OF THE LIQUID DURING THE PISTON WORKING STROKE; A CYLINDRICAL BUSHING TO OPEN AND CLOSE SAID OPENINGS AND HAVING RECIPROCATING MOTION ALONG THE EXTERNAL SURFACE OF SAID CYLINDER; JACKS SECURED TO THE EXTERNAL SURFACE OF SAID CYLINDER, THE RODS OF SAID JACKS BEING RIGIDLY CONNECTED TO THE CYLINDRICAL BUSHING WITH ONE OF THE SPACES OF EACH JACK BEING CONNECTED TO A MAIN LINE DELIVERING THE LIQUID UNDER PRESSURE FOR TRAVEL OF THE PISTON, AND THE OTHER SPACE OF EACH JACK COMMUNICATING WITH SAID RECEIVER FILLED WITH COMPRESSED GAS; A COMMAND VALVE INCLUDING A PROTRUDING PIN ENTERING THE LOW PRESSURE CHAMBER IN THE FACE WALL OF SAID SYLINDER, LIMITING THE LOW PRESSURE CHAMBER AND CONNECTING THE HYDRAULIC SPACE OF EACH SAID JACK WITH THE ATMOSPHERE WITH SAID PISTON ACTING UPON SAID PROTRUDING PIN OF SAID COMMAND VALVE.

Claim 2

A DEVICE FOR BUILDING UP HIGH PRESSURE PULSES OF LIQUID, COMPRISING AT LEAST ONE CYLINDER AND ONE PISTON HOUSED IN SAID CYLINDER; SAID CYLINDER HAVING AT ONE SIDE OF THE PISTON A FIRST SPACE CONNECTED THROUGH AN OPENING IN THE CYLINDER WITH AT LEAST ONE RECEIVER FILLED WITH COMPRESSED GAS AND SERVING AS A LOW-PRESSURE CHAMBER; SAID CYLINDER HAVING AT THE OTHER SIDE OF THE PISTON A SECOND SPACE IN THE BODY OF THE CYLINDER FACE PORTION, FILLED UP WITH LIQUID AND PROVIDED WITH AT LEAST ONE OUTLET OPENING; SAID SECOND SPACE HAVING A CROSS-SECTION CORRESPONDING TO THE CROSS-SECTION OF THE PISTON AND SERVING AS A HIGH PRESSURE CHAMBER, SAID HIGH PRESSURE BEING BUILT UP AS A RESULT OF THE IMPACT OF SAID PISTON UPON THE LIQUID, SAID PISTON INCLUDING IN THE FACE PORTION AT THE SIDE OF THE HIGH PRESSURE CHAMBER A TAPER-SHAPED LUG; CIRCULAR GROVES BEING PROVIDED ON THE EXTERNAL SURFACE OF THE PISTON PORTION ENTERING THE HIGH-PRESSURE CHAMBER; AN ANGULAR THROUGH CHANNEL BEING PROVIDED IN SAID PISTON AND CONNECTING ITS SIDE SURFACE WIOTH THE FACE SURFACE AT THE SIDE OF THE LOW PRESSURE CHAMBER; A NON-RETURN VALVE WITH A THROUGH OPENING BEING PROVIDED IN THE PLUNGER OF SAID NON-RETURN VALVE LOCATED IN SAID ANGULAR CHANNEL; SAID CYLINDER HAVING IN THE SIDE WALL OF THE HIGH PRESSURE CHAMBER AT LEAST ONE OPENING FOR DELIVERING THE LIQUID UNDER PRESSURE FOR FORCED TRAVEL OF SAID PISTON IN THE DIRECTION OF THE LOW-PRESSURE CHAMBER, OPENINGS SERVING FOR THE DISCHANGE OF THE LIQUID DURING THE PISTON WORKING STROKE; A CYLINDRICAL BUSHING TO OPEN AND CLOSE SAID OPENINGS AND HAVING RECIPROCATING MOTION ALONG THE EXTERNAL SURFACE OF SAID CYLINDER; JACKS SECURED TO THE EXTERNAL SURFACE OF SAID CYLINDER, THE RODS OF SAID JACKS BEING RIGIDLY CONNECTED TO THE CYLINDRICAL BUSHING WITH ONE OF THE SPACES OF EACH JACK BEING CONNECTED TO A MAIN LINE DELIVERING THE LIQUID UNDER PRESSURE FOR TRAVEL OF THE PISTON, AND THE OTHER SPACE OF EACH JACK COMMUNICATING WITH SAID RECEIVER FILLED WITH COMPRESSED GAS; A COMMAND VALVE INCLUDING A PROTRUDING PIN ENTERING THE LOW PRESSURE CHAMBER IN THE FACE WALL OF SAID SYLINDER, LIMITING THE LOW PRESSURE CHAMBER AND CONNECTING THE HYDRAULIC SPACE OF EACH SAID JACK WITH THE ATMOSPHERE WITH SAID PISTON ACTING UPON SAID PROTRUDING PIN OF SAID COMMAND VALVE.
