| The stator for a helical gear device is formed of a plurality of duplicate disks. The disks each include a convoluted cavity having equally spaced symmetrically radially extending lobes for receiving the convex lobes of the rotor. The disks are assembled into the form of a stator by inserting the disks about a mandrel which includes convoluted lobes, so that the convoluted cavities of the disks follow the shapes of the lobes of the mandrel, thereby causing the disks to be progressively radially offset with respect to one another along the length of the stator. The stacked disks are inserted into a heated cylindrical housing so that the housing forms a shrink fit about the disks. The disks and housing are further connected by brazing, and the disks optionally have openings formed between the lobes which function as convoluted channels through the assembled stator for the passage of liquid, wiring, etc. through the stator. | ||||||

Each spacer has a tubular wall, an inlet end with an internal annular flange and an outlet end defined by a circumferential edge of the tubular wall. An elastomeric stator segment is housed in each spacer. Each stator segment has adjacent an outlet end thereof a circumferential external lip portion and has a contoured cavity therethrough generally coaxial with the pump barrel and adaptable to rotatably receive a progressing cavity pump rotor therein. The lip portion of each stator segment is captured between a spacer outlet end circumferential edge and the next adjacent spacer annular flange portion so that the elastomeric stator segments are retained in serial position within the pump barrel by the spacers permitting the spacers and stator segments to be easily removed from the pump barrel for repair and replacement. | ||||||
| 174 | Control curve for variable delivery compressor | US802115 | 1997-02-19 | US5689960A | 1997-11-25 | David E. Bearint |
| A method for adjusting an air conditioner compressor for a particular vehicle application involves selecting the proper control curve. The control curve is a graph of suction inlet pressure verses discharge pressure. The graph has a linear portion over which increased discharge pressure decreases suction pressure. The low demand condition at which suction pressure is highest and discharge pressure lowest may result in an evaporator outlet pressure that is too high or too low. To change the evaporator outlet pressure, the control valve for the compressor is adjusted or replaced to vary the slope of the linear portion of the control curve. Varying the slope will change the maximum suction pressure to reach an optimized solution under low demand conditions. The slope is varied by changing a bias pin in the modular control valve to one of a different diameter. The bias pin is one factor that controls the opening and closing of the valve to vary the capacity of the compressor. | ||||||
