Hydrostatic transmissions and hydrostatic actuators are then examined in more detail with coverage of pumps and motors, hydrostatic solutions to single-rod actuators, energy management and efficiency and dynamic response. Consideration is also given to current and emerging applications of hydrostatic transmissions and actuators in automobiles, mobile equipment, wind turbines, wave energy harvesting and airplanes. End of chapter exercises and real world industrial examples are included throughout and a companion website hosting a solution manual is also available. Hydrostatic Transmissions and Actuators is an up to date and comprehensive textbook suitable for courses on fluid power systems and technology, and mechatronics systems design"--$cProvided by publisher. 606 $aOil hydraulic machinery 606 $aFluid power technology 606 $aHydrostatics 606 $aPower transmission 606 $aActuators 608 $aElectronic books. 615 0$aOil hydraulic machinery. 615 0$aFluid power technology. 615 0$aHydrostatics. 615 0$aPower transmission. 615 0$aActuators. 676 $a620.1/06 686 $aTEC009070$2bisacsh 700 $aCosta$b Gustavo K.$0170261 702 $aSepehri$b Nariman 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910460810503321 996 $aHydrostatic transmissions and actuators$91947468 997 $aUNINA
