    摘要: The point of tangency of the tip circle of the male rotor and the root circle of the female rotor is used as a starting point in generating the series of curves defining the male and female conjugate rotor profiles. The present invention provides: reduced viscous drag through the use of a departure angle; strengthened female lobes by controlling thickness along the pitch circle; opened root of male rotor to enhance manufacturability and tool life; a tortuous leakage path for gas traveling from a high pressure thread to a low pressure thread; better control of root diameter; and control of the pressure angle independently of the other variables.

    摘要: An improved geometry for scroll wrap inner portion includes a groove which facilitates opening of the compression chambers to the discharge ports early in the cycle of the orbiting scroll. Stated one way, a forward end of the scroll wrap tip is thinner than a portion spaced from the forward end. A first curve defines the forwardmost end of said tip and extends to a forward ledge. A second circular curve is spaced from the forward ledge and extends to a rear ledge. An intermediate curve connects the forward and rear ledges. The rear curve is centered on a second radius, and if the second radius were extended beyond the rear ledge, the extension would move to a position spaced from the forward ledge and towards the opposed wrap. The swing radius for the scroll compressor wrap measured begins at the position wherein the forward ledge of one wrap faces the rear ledge of an opposed wrap begins on one side of zero, then crosses zero with an increasing scroll wrap, and then moves to an opposed side of zero. The inventive scroll compressor wrap achieves more rapid and smooth opening of the compression chambers to the discharge ports.

    摘要: Two housing members and the stator are precision machined on diameters and assembled such that the machined diameters coact to locate the members which then serve as a reference location for the subsequently assembled parts. The present invention reduces the number of critical machined features compared to a piloted assembly.

    摘要: The annular piston of a rolling piston compressor coacts with a groove in valving action such that the groove serves as a supplemental discharge flow area but gas therein is prevented from constituting part of the suction flow. The groove may be in the motor end bearing and/or pump end bearing and permits flow from the compression chamber to the interior of the piston which is in fluid communication with the interior of the shell while the compression chamber is undergoing discharge.

    摘要: An end shell for a hermetic compressor is formed from a sheet of metal. When formed, the end shell has a spherical surface which extends for at least 230.degree. of the circumference of said end shell. If necessary or desired, a portion of up to 90.degree. of the circumference of said end shell can be formed as a cylindrical segment in order to provide a radial discharge or the like.
