Information:

When the vibratory operating parameters are as described above, solenoid "C1" (2) and front vibratory solenoid (12) are energized. In this case, supply oil is directed out port "A" of the vibratory pump and into port "B1" of the vibratory and brake control valve. Inside the vibratory and brake control valve, the passage on the spring side of rear drum bypass valve (11) is open to tank across the front vibratory solenoid. However, initially, the rear drum bypass valve remains closed.Internal passages in the vibratory and brake control valve direct the supply oil out port "B" of the valve. From there, oil is directed to port "B" of rear vibratory motor (27). The outlet side of the rear vibratory motor is connected to two locations. The first connection is to port "A" of front vibratory motor (23). The second connection is to port "P" of the vibratory and brake control valve. Oil in the second connection acts against rear drum bypass valve (11), in opposition to a spring.When front vibratory solenoid (12) is energized, system pressure causes rear drum bypass valve (11) to shift against the spring force. In this case, port "B1", port "B", and port "P" of the vibratory and brake control valve are connected to port "A" of vibratory pump (6). Under these conditions, the pressure at port "A" and port "B" of the rear vibratory motor is equal, and the motor does not rotate. Since port "B" of front vibratory motor (23) and port "B" of the vibratory pump are connected through the vibratory and brake control valve, the front vibratory motor rotates.Inside vibratory pump (6), main relief valve (19) and pressure limiter valve (17) in the high-pressure loop limit the maximum system pressure. Makeup valve (21) in the low-pressure side of the system allows charge oil to flow into the low-pressure side of the hydrostatic loop. Flushing spool (25) and flushing relief valve (26) direct oil from the low-pressure side of the hydrostatic loop into the motor case drains.
