Abstract
A hydraulic deceleration control for a hydraulic motor includes a pilot operated control valve for controlling fluid flow through a pair of motor lines connected to the opposite sides of the hydraulic motor. A valve device is disposed to communicate a source of pressurized fluid to a fluid energy storage device when the control valve is in its open position and to release the pressurized fluid contained in the storage device when the control valve is moved from the open position to its closed position. A throttle orifice releases the fluid from the storage device at a controlled flow rate. A pilot operated diverter valve is disposed in series with an orifice disposed between the motor lines to control fluid flow through the orifice and has a spring disposed at a first end resiliently biasing the diverter valve to its closed position. The storage device is in communication with a second end of the diverter valve when the valve device is releasing the fluid from the storage device so that the diverter valve moves to and is maintained in its open position while fluid is being released from the storage device.
