The approximate pre- charge pressure is determined based on the transition pressure.

The method precharges the molding medium (42) within a fill head unit (12) to a precharge pressure.

Initial precharge pressure of 1000± 100 kPa at a displaced volume of 0 cm3

Initial precharge pressure of 500± 100 kPa at a displaced volume of 0 cm3

The recirculation pumps of brake systems with a precharging device are subject to heavy loads from the precharging pressure and are subject to premature wear.

Increase pressure to 10,000 psi (Maximum Working Pressure), allow to

A pressure relief valve and a check valve are in pressure communication between the gas precharge pressure chamber and a pressure relief chamber.

The first piston separates an hydraulic fluid chamber and a gas precharge pressure chamber.

The accumulator (26) has a preloading pressure, which is at least 0.3 MPa lower than the mean operating pressure of the hydraulic cylinder (10).

During the injecting of the molding medium (42) into the preform (18), the method further increases the pressure of the molding medium to a pressure greater than the precharge pressure.

One of the actuator chambers is maintained at a fixed pre-charged pressure of the accumulator, and the operation of the pump controls the pressure in, and volume of, the other chamber.

Each belt is sewn directly over the pad, to ensure it is constantly under preload pressure.

A system (100) including a hydraulic accumulator (102), a pressure sensor (104), a fluid source (106) and a data processor (108) to detect a pre- charge pressure is provided.

Clevidipine does not reduce cardiac filling pressure (pre-load), confirming lack of effects on the venous capacitance vessels.

A soft pusher member (14) is disposed at location between the stent-carrying and flexible sections to absorb preload pressure and to urge the stent from the distal end of the introducer catheter.
