Abstract

In an hydraulic power system (50, Fig. 1) for using in a valve testing apparatus comprising an hydraulic fluid reservoir 52 and an hydraulic pump 54 operative from time to time to charge a large capacity hydraulic accummulator 56 capable of storing hydraulic fluid for several valve testing operations, a pressure regulator 74 is operative to deliver hydraulic fluid for valve testing operations. Actual operation is controlled by fluid flow control means, for example a fluid routing valve 80 of a sliding spool type. Charging of the accummulator 56 may be monitored by a pressure gauge 68, and a pressure gauge 84 may monitor applied operating pressure to enable adjustment of regulator 74. <IMAGE>
