Direct Displacement Control (DDC)
The Direct Displacement Control can be located on either side of a Series 40 - M25, M35, or M44 pump. It provides a simple, positive method of control. Movement of the control shaft causes a proportional swash plate movement, thus varying the pump's displacement from full displacement in one direction to full displacement in the opposite direction. Some applications (generally vehicle propel) will require a provision for non-linear control input to reduce control sensitivity near neutral. Damping or frictional forces may be necessary to produce desirable control feel. Neutral position is not factory set, nor is there any internal neutral return mechanism. The application must include provisions for all control linkage and neutral return functionality.
Manual Displacement Control (MDC)
The Manual Displacement Control converts a mechanical input signal to a hydraulic signal with a spring centered 4- way servo valve, and ports hydraulic pressure to either side of a double acting servo piston. The MDC provides output flow to the servo piston in proportion to the angular position of the control handle. The servo piston tilts the cradle swash plate, thus varying the pump's displacement from full displacement in one direction to full displacement in the opposite direction. Due to normal operating force changes, the swash plate tends to drift from the position preset by the machine operator. Drift, sensed by the feedback linkage system connecting the swash plate to the control valve, will activate the valve and supply pressure to the servo piston, maintaining the swash plate in its preset position.
Hydraulic Displacement Control (HDC)
The Hydraulic Displacement Control uses a hydraulic input signal to operate a spring centered 4-way servo valve, which ports hydraulic pressure to either side of a double acting servo piston. The servo piston tilts the cradle swash plate, thus varying the pump's displacement from full displacement in one direction to full displacement in the opposite direction. The HDC provides output flow in proportion to a hydraulic command signal. This allows for remote control of the machine with a hydraulic pressure source rather than with mechanical linkage. With no command signal, the control is in or will return to neutral position.
Electrical Displacement Control (EDC)
The Electrical Displacement Control is similar to the Hydraulic Displacement Control, but uses an electro-hydraulic Pressure Control Pilot (PCP) valve to control the pilot pressure. The PCP valve converts an electrical input signal to a hydraulic signal to operate a spring centered 4- way servo valve, which ports hydraulic pressure to either side of a double acting servo piston. The servo piston tilts the cradle swash plate, thus varying the pump's displacement from full displacement in one direction to full displacement
in the opposite direction. The EDC provides output flow in proportion to a DC electrical command signal (current). These controls are suited for applications where remote or automatic control of system function is required, or where closed loop feedback is needed. With no electrical command signal, the control is in or will return to the neutral position.
