Abstract
The plunger of the high - pressure cylinder has a driving ram coupled at one end. The coupling includes an annular groove on the plunger end and a two - piece collar with inner ridge. A cup - shaped collar retainer and a snap ring retain the collar in the ram. The coupling eliminates bolting. The open cylinder end is shouldered and grooved to receive a sleeve, a multi - piece key, a seat, and a seal which assemble to receive, center, and seal the plunger in the high pressure cylinder. The seal assembly eliminates the need for a bolted cylinder end.
