초록

A valve assembly which is effective for filling a system with pressurized fluid and metering from the pressurized system a predetermined amount of pressurized fluid. The valve assembly includes a valve body comprising a primary chamber and a valve member adapted to move within the primary chamber. The primary chamber communicates with a source of pressurized fluid and also communicates with a working cylinder. The valve member is responsive to a first pressure of the source of pressurized fluid to allow the working cylinder to achieve a maximum stroke. T...
