PRINCIPLE OF OPERATION Oil directed to the rod end of the cylinder assenbly flows through the check valve in the outside piston 20 as long as the ball 22 is held off its seat 23 by the valve plurver 30 This causes the piston to retract pulling the draw rod back and expanding the gripoer When the piston has moved about 3 8 away fram the outside piston the ball seats trapping oil between the pistons and the two pistons move back as a unit pulling both the griper and the draw rod with no further expansion of gripper When a tube is being pulled the pres sure between the pistons starts to rise as soon as the grip per starts to grip the tube pushing the valve plunger 30 back against its spring 32 When enough pressure has built uo to fully grip the tube the valve plunger has been pushed back far enough to allow the check valve in the out side piston to seal off so that expansion stops and the tube is pulled by the gripper and not the draw rod On the reset stroke the outside piston stops when it bottams cut on the case The oil between the pistons escapes past the ball in the outside piston When the piston 29 bottoms out the system pressure rises enough to trip the internal pump unloader and the pnp shifts back to its idle position Page 9 TROUBLE SHOOTING SEE SERVICE MANUAL NUMBER 90120 IM FOR HYDRAULIC PUMP MODEL PATP 9400 P Gripper slips out of tube 1 Grippers worn out teeth without gri
