Series ninety axial piston variable displacement pumps are of cradle swash plate layout with variable displacement, and are supposed for closed circuit apps. The movement rate is proportional to the pump input velocity and displacement. The latter is infinitely adjustable in between zero and highest displacement. Movement direction is reversed by tilting the swash plate to the opposite aspect of the neutral (zero displacement) situation.

CZPT – Circuit Diagram, Nomenclature and Description, three-Situation (FNR) CZPTtric Management, Possibilities DC, DD
The 3-Situation (FNR) manage employs an electrical enter signal to change the pump to a full stroke placement.
A variety of orifice measurements is offered for the Series 90 CZPTtric Displacement Manage to aid in matching the rate of swash plate reaction to the acceleration and deceleration demands of the software. Tests ought to be carried out to decide the appropriate orifice variety for the preferred response.
CZPTtric Displacement Handle (EDC), Choices KA, KP
The electric displacement management uses an electro-hydraulic Pressure Management Pilot valve to control the pilot force. The Strain Control Pilot valve converts an electrical input signal to a hydraulic input sign to work a 4-way servo valve, which ports hydraulic force to either aspect of a double acting servo piston. The servo piston tilts the cradle swash plate, hence varying the pump’s displacement from total displacement in 1 path to total displacement in the opposite direction. The manage has a mechanical suggestions mechanism which moves the servo valve in relation to the enter sign and the angular place of the swash plate. The electrical displacement control is made so the angular rotation of the swash plate (pump displacement) is proportional to the electrical enter signal. Thanks to typical working drive modifications, the swash plate tends to drift from the position preset by the device
operator. Drift, sensed by feedback linkage program connecting the swash plate to the handle valve, will activate the valve and supply force to the servo piston, keeping the swash plate in its preset placement.
CZPT Displacement Control (HDC), Choice HF
The hydraulic displacement control makes use of a hydraulic enter signal to work a four-way servo valve, which ports hydraulic strain to either facet of a double acting servo piston. The servo piston tilts the cradle swash plate, thus different the pump’s displacement from complete displacement in a single course to full displacement in the opposite path. The control has a mechanical comments mechanism which moves the servo valve in relation to the input signal and the angular rotation of the swash plate. The hydraulic displacement
management is developed so the angular position of the swash plate (pump displacement) is proportional to the hydraulic enter signal pressure. Because of to regular running power modifications, the swash plate tends to drift from the place preset by the device operator. Drift, sensed by comments linkage technique connecting the swash plate to the management valve, will activate the valve and offer stress to the servo piston, maintaining the swash plate in its preset position.
Handbook Displacement Control (MDC), Possibilities MA, MB
The guide displacement control system converts a mechanical enter sign to a hydraulic sign that tilts the cradle swash plate via an angular rotation various the pump’s displacement from full displacement in 1 route to entire displacement in the opposite course. The handbook displacement handle has a mechanical suggestions mechanism which moves a servo valve in the correct partnership to the enter signal and the angular placement of the swash plate. The guide displacement manage is developed so that the angular rotation of the swash plate is proportional to the mechanical input signal. The handle is created with an inner override mechanism which allows the mechanical input to be moved at a faster price than the movement of the swash plate with no damage to the handle.
Non-linear Guide Displacement Handle (MDC), Alternative NA
The handbook displacement management unit converts a mechanical input sign to a hydraulic signal that tilts the cradle swash plate through an angular rotation varying the pump’s displacement from full displacement in one particular course to entire displacement in the opposite direction. The manual displacement management has a mechanical suggestions system which moves a servo valve in the appropriate partnership to the input signal and the angular place of the swash plate. The manual displacement manage is designed so that the angular rotation of the swash plate is progressive to the mechanical enter sign. The control is made with an interior override mechanism which makes it possible for the mechanical input to be moved at a faster rate than the motion of the swash plate with out hurt to the handle.
