the gasket has been placed into the connection, the bolts are loosely installed and then tightened in stages as recommended by ASME PCC-1. [2] Bolt tightening in stages, utilizing a cross-pattern sequence, allows for uniform distribution of the stresses in the gasket and throughout the mating flanges. This prevents damage to the gasket surfaces and increases the success rate of the bolted connection. For problematic flange connections the use of bolt-torque tightening techniques was recommended and implemented.

This rotary valve design for internal combustion engines is claimed to overcome the problems of valve area, variable timing potential, sealing and lubricant consumption associated with previous designs.
not covered in any detail. This would presumably limit the temperature range of this device. The effect that temperature variations have on the pressure in the hydraulic circuit -when the pressure is locked in -is also not covered. This latter factor could cause very significant pressure variations.
