Patent
Rotary hydrostatic radial piston machines
TL;DR: A rotary radial piston pump or motor has a cylinder barrel rotating on a fixed pintle with a fluid exit at the fixed end of the pintle and an inlet at the opposite free end.
Patent
Rotary hydrostatic machines or transmissions
TL;DR: In this paper, the authors describe a hydrostatic machine including a casing containing a rotary member 12 having radial cylinders 20 each with a piston 21 engaging a track ring 23, where both input and output shafts are connected either hydraulically through the transmission rotary members 12 or mechanically through a bypass shaft 10 and clutch 50 for reducing machine heat losses.
Patent
Coaxial hydraulic actuator system
TL;DR: In this article, a coaxial hydraulic actuator system utilizes a vane pump close coupled to a Vane actuator, which includes a rotatable housing which is perpendicularly movable by a control piston to direct fluid flow through first and second fluid conduits in a pintle port transfer shaft.
Patent
Double-flow hydrostatic radial piston engine with axial flow, thrust compensation, and shaft bearing
Gerhard Fähnle,Günther Nagel +1 more
TL;DR: In this article, a hydrostatic radial piston engine with two rotors that are supported on an axle so that they can rotate easily thereon is described. But the rotors have a plurality of radial bores with displacement elements (pistons with slide ring) therein, sliding on the inside of a piston ring.

Patent
Hydraulic motor system
TL;DR: In this paper, a hydraulic motor system minimizes wasted power by using a plurality of fixed displacement hydraulic motors to drive a drive shaft in a cooperative manner, selectively switched into operation in response to variations in fluid pressure.
Patent
Variable delivery vane pump
TL;DR: In this paper, the authors describe a vase device which when employed as a pump has variable delivery and, correspondingly, when applied as a motor has variable speed, but it is to be understood that the device will be termed a pump.
Patent
Control mechanism for hydraulic transmissions
TL;DR: In this paper, the authors propose a means for controlling the speed of output developed by the transmission and the torque obtained from the transmission, where the motor and pump elements are variable in their displacement.
Patent
Rotary piston engine especially for fluid gears
TL;DR: In this paper, a rotary piston engine with blades or vanes is described, in which the piston drum rotating about a central journal is surrounded by a rotatable housing forming the boundary wall of the working chamber.
Patent
Variable capacity sliding vane pump
TL;DR: In this article, a positive displacement eccentric sliding vane type is used for a pump with radially or similarly slidable vanes operating in conjunction with abutments, where the vanes are assumed to be radially and similarly inclined.
