Hydraulic pulsation absorption system

Claim 1

A PULSATION ABSORPTION SYSTEM FOR ABSORBING PULSATIONS OF HYDRAULIC PRESSURE IN A HYDRAULIC LINE WITH A PARTICULAR HYDRAULIC PRESSURE, SAID PULSATION ABSORPTION DEVICE COMPRISING, IN COMBINATION, A CLOSED CYLINDRICAL SHELL HAVING TWO ENDS, A BOTTOM, A CENTERLINE, AND A TOP THROUGH WHICH AN AIR INLET HOLE PASSES; A PIPE SECTION EXTENDING THROUGH THE CYLINDRICAL SHELL BETWEEN THE CENTERLINE OF THE CYLINDRICAL SHELL AND THE BOTTOM OF THE CYLINDRICAL SHELL, SAID PIPE SECTION HAVING ITS CENTERLINE PARALLEL TO AND IN THE SAME VERTICAL PLANE AS THE CENTERLINE OF THE CYLINDRICAL SHELL, HAVING ITS ENDS EXTENDING OUTSIDE OF THE CYLINDRICAL SHELL AND INSERTED INTO THE HYDRAULIC LINE, AND HAVING A SLOT EXTENDING THROUGH THAT PORTION OF ITS LENGTH WITHIN THE CYLINDRICAL SHELL AND ALONG THAT SIDE NEAREST THE BOTTOM OF THE CYLINDRICAL SHELL; TWO BAFFLE PLATES POSITIONED WITHIN THE CYLINDRICAL SHELL ABOVE THE CENTERLINE OF THE CYLINDRICAL SHELL, THE SAID TWO BAFFLE PLATES EXTENDING FROM OPPOSITE SIDES OF THE CYLINDRICAL SHELL, LYING IN THE SAME HORIZONTAL PLANE, AND DEFINING WITH THE TWO ENDS OF THE CYLINDRICAL SHELL A RECTANTULAR OPENING AND WITH THE TWO ENDS AND THE TOP OF THE CYLINDRICAL SHELL A VOLUME; AND MEANS RESPONSIVE TO THE PARTICULAR HYDRAULIC PRESSURE IN THE HYDRAULIC LINE FOR INJECTING THROUGH THE AIR INLET HOLE THAT VOLUME OF AIR NECESSARY TO FILL THE VOLUME DEFINED BY THE TWO BAFFLE PLATES AND THE TWO ENDS AND THE TOP OF THE CYLINDRICAL SHELL EACH TIME THE PARTICULAR HYDRAULIC PRESSURE IS DEVELOPED WITHIN THE HYDRAULIC LINE.
