PROMENLJIVE RADNE ZAPREMINE; ZA OTVORENE SISTEMEVARIABLE DISPLACEMENT; FOR OPEN - LOOP SYSTEMS

Izuzetno kompaktna i laka konstrukcija sa nagibnim blokom

Sumarna regulacija snage u podru~ju pritiska do 350 bar

Robusna konstrukcija cilindarskog bloka i sna`no ule`i{tenje pogonskog vratila

Nizak nivo {uma

Jednostavno pode{avanje radne zapremine zaokretanjem ocilindarskog bloka za maksimalni ugao 28

Naleganje cilindarskog bloka na razvodnu plo~u zavisno je od pritiska, usled ~ega je curenje malo, a izgubljena snaga neznatna.

Jednostavno priklju~enje na pogonsku ma{inu preko SAE prirubnice.

Po{to je pumpa dvostrujna i samousisavaju}a, to obe pumpe usisavaju dva jednaka odvojena protoka (Q/2). Protoci i jedne i druge pumpe se istovremeno pode{aavaju u zavisnosti od pritiska u svakoj od grana. Zbir oba pritiska dejstvuje na regulator, kao signal, tako da zbiru pritisaka uvek odgovara odre|eni zbir protoka. Ukoliko u praksi protok iz jedne grane ka

Extremely compact design, bent axis design

Summary power regulation within 350 bar pressure range

Robust construction of the cylinder block and sturdy bearing of driving shaft

Simple connection to driving machine through a SAE flange

Noiseless operationPossibility of connection of an additional pump (either single-flow or double-flow type)

oMaximum swing angle 28

Resting of cylinder block of distribution plate depends on working pressure, so it causes leakage to be small and loss of power negligent
