Brake Circuit with Hydraulic Motor

This figure is an example of a motor that turns both directions. With the solenoid valve in position 1, the hydraulic motor turns right. After that, the solenoid valve is in the middle position, but the hydraulic motor keeps working as a pump because of inertia. Discharged working fluid runs through the check valve 4, and returns to the reservoir with back pressure given by the relief valve. The primary side of the motor becomes low pressure, thus working fluid through the check valve ® is supplied into the line. In the case of a left turn, the check valve 2 and 5 are used.
