AIR-OPERATED EXPANDER-GENERATOR PLANT Russian patent published in 2014 - IPC F25B11/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to gas pressure control equipment. Proposed plant comprises drive air actuator. The latter consists of housing with inlet and outlet pipes, jacket with inlet and outlet pipes and generator with stator and rotor arranged inside said jacket. Air actuator incorporates two gears with pins that features external engagement. One of said pins is composed by drive shaft. Rotor and splined coupling are fitted on driven shaft opposite ends. Drive and driven shafts are coupled by splined coupling. Jacket bottom has groove to make the thrust bearing seat. Flanged spool is fitted between jacket bottom and housing cover. Splined coupling is arranged to interact by its bottom end with thrust bearing. Inlet pipe is composed by V-like tee with central and two side branches jointed to the housing. Shaped ledge is made inside said housing between lateral branches. Ledge mirror plane is located perpendicular to the plane extending via gear pivoting pins at equal distance from said pins. Jacket inlet pipe is connected to the housing outlet pipe. Axes of V-shape tee lateral branches are located in symmetry about shaped ledge mirror plane.

EFFECT: higher efficiency.
