35.1. HAT Type A

The schematic diagram of the Type A analysis model is shown in Figure 35.2.

  • The spring force and the hydraulic force react against the motion of plunger.

  • The motion of plunger is assumed to act in the same direction as the motion of cylinder.

  • The check ball acts upon by the spring force and the hydraulic force from the plunger.

  • The motion of the check ball is also assumed to act in the same direction as the plunger.

  • The check ball is contacted to the plunger.
