Flow Combiner Valve Manual Instructions Extract:
1. During combined operation arm roll-in and travel, pilot pressure shifts travel (right) spool (5), travel (left) spool (4), arm 1 spool (10), and arm 2 spool (7).
2. At the same time, the travel (right) pilot pressure shifts the flow combiner valve control spool in the signal control valve.
3. Pressure oil from the pilot pump flows to port SL in the flow combiner valve through the flow combiner valve control spool and is routed to spool (1).
4. When pressure at port SL increases beyond the spring (2) force, spool (1) compresses spring (2) and moves to the left.
5. Pressure oil from pump 1 (8) flows to travel (right) spool (5). In addition, pressure oil from pump 1 (8) flows to travel (left) spool (4) through spool (1).
6. Pressure oil from pump 2 (9) flows to arm cylinder (11) through arm 1 spool (10) and moves the arm at this time.
7. Consequently, pressure oil from pump 1 (8) is equally supplied to both left and right travel motors and the machine can travel straight.
