The A4VG axial piston variable pump in swash plate layout for hydrostatic shut circuit transmissions
– Movement is proportional to drive pace and displacement and is infinitely variable
– Output movement raises with the swivel angle of the swash plate from to its optimum worth
– Movement direction changes easily when the swash plate is moved by way of the neutral placement
– A wide variety of highly adaptable manage devices is offered for various management and regulating capabilities
– The pump is geared up with two strain-reduction valves on the substantial stress ports to safeguard the hydrostatic transmission (pump and motor) from overload
– The high-strain reduction valves also perform as boost valves
– The built-in increase pump acts as a feed and handle oil pump
– The highest increase force is minimal by a built-in improve stress relief valve
– The integral pressure cut-off is CZPT
