Abstract: A rotary actuator includes a central housing; an output shaft that extends through the central housing; a vane that is mechanically coupled to the output shaft and divides the central housing into a first chamber and a second chamber; and a flow control mechanism that is moveable within the central housing and including a high pressure port and a low pressure port for communicating hydraulic fluid into and from the first and second chambers. The flow control mechanism is moveable to position the high pressure port and low pressure port relative to the first chamber and the second chamber for communication of the hydraulic fluid, thereby generating a pressure differential across the chambers. The vane rotates within the central housing in response to the pressure differential, and rotation of the vane drives the output shaft. A motor is configured to receive control signals to drive the movement of the flow control mechanism.

Abstract: A horizontal non-barrier pressure vessel including a first chamber and a second chamber that are separated by a divider. The first chamber includes a first end proximal an opening, a second end distal the opening, and an uppermost surface that extends horizontally along the length of the first chamber or is inclined upwardly from the first end to the second end. The second chamber operatively adjoins the first chamber at the second end opposite the opening. A flow passage extends across the divider and enables fluid communication with the first chamber at an upper region of the second end and with the second chamber at a lower region. The divider may include vertically oriented bottom and top baffles being spaced to form the flow passage. The pressure vessel may include a plurality of segments and/or chambers sequentially arranged along a horizontal course.
