Abstract
A high-pressure cylinder of a liquid jet cutting system can include a first end portion, a second end portion, and a central bore configured to receive a plunger. The first end portion can have a first tapered surface configured to form a seal with a mating surface of a check valve when the high-pressure cylinder is in a first orientation, and a first annular surface configured to bear against a mating surface of a pump when the high-pressure cylinder is in a second orientation rotated 180 degrees end-over-end from the first orientation. The second end portion can have a second annular tapered surface configured to form a seal with the mating surface of the check valve when the high-pressure cylinder is in the second orientation, and a second annular surface configured to bear against the mating surface of the pump when the high-pressure cylinder is in the first orientation.
