A sealed, electrically controlled compressor provides for two way optical data transmission to and from its sealed interior. An optical window, securely sealed through the compressor shell, and a pair of optical devices located to either side of the window, allow data transfer with no separate lines piercing the shell.

Electrically driven compressor with contactless control

A scroll compressor 10 having a fixed scroll 18, an orbital scroll 70 and a drive 90 and 94 for moving the orbital scroll in a generally circular orbit. The scrolls 18 and 70 have end plates 24 and 72, with flat surfaces 26 and 76 and involute wraps 28 and 74. The wraps have inside flank surfaces 30 and 77, outside flank surfaces 32 and 78 and axial tips 34 and 80. A portion 164 of the axial tip 34 of the fixed scroll 18 adjacent the outside flank surface 32 is recessed from an adjacent portion of the axial tip that is adjacent to the inside flank surface 30. A portion 170 of the axial tip 80 of the orbital scroll 70 adjacent outside flank surface 78 has a surface in a plane that is recessed from an adjacent portion of the axial tip that is adjacent to the inside flank surface 77.

Scroll type machine with improved wrap radially outer tip

A scroll type compressor 10 having a housing 12, a non-orbital scroll 24, an orbital scroll 22, an orbital scroll drive 50, an anti-rotation assembly 54, and an axial thrust load assembly. The non-orbital scroll 24 is mounted in a rear casing of the housing 12. The orbital scroll 22 cooperates with the non-orbital scroll to form fluid pockets 46 and 48. The orbital scroll 22 is driven by an orbital drive 50 to move the fluid pockets to the center of the scrolls and compress the fluid sealed in the pockets. The anti-rotation assembly 54 includes cups 94 and pins 96 which define a circular orbit that is followed by bearings 104 on pins 100. The scroll drive 50 includes a drawn steel cup 70 that is driven by a drive shaft 82. A first bore 72, with an axis offset from the axis of the drive shaft 82, receives a knuckle bushing 62 which is rotatably attached to the orbital scroll 22. A balance weight 88 is journaled on the orbital scroll 22 and is driven by pin 86. The sliding connection between the cup 70 and the knuckle bushing permits some change in the orbit radius R.sub.o of the orbital scroll 22. The cups 94 are sized relative to the bearings 104 to accommodate changes in the orbit radius R.sub.o of the orbital scroll 22.

Scroll compressor orbital scroll drive and anti-rotation assembly

A scroll type compressor 10 having a housing 12, a non-orbital scroll 24 mounted in the rear casing of the housing 12 and an orbital scroll 22. The scrolls 22 and 24 cooperate to form fluid pockets 46 and 48. An orbital drive 50 orbits the orbital scroll 22 to move the fluid pockets 46 and 48 to the center of the scrolls and compress the fluid sealed in the pockets. An anti-rotation assembly 54 is connected to the housing 12 and to the orbital scroll 22 to prevent rotation and permit orbital movement of the orbital scroll. An axial thrust load assembly 56 including a baffle plate 114 with continuous pressure chamber flanges 120 and 122 are mounted in the rear section 16 of the housing 12. The flanges 120 and 122 are telescopically received in grooves 124 and 126 in the end plate 28 of the non-orbital scroll 24. V-shaped spring seals 130 are placed in the grooves 124 and 126. High pressure fluid in the inner discharge chamber and medium pressure which enters toroidal intermediate pressure chamber 138 through passage 140 exert an axial force on the scrolls. The non-orbital scroll 24 is mounted on fixed pins 134 which allow axial movement of the scroll. Springs 144 axially bias the non-orbital scroll 24 toward the orbital scroll 22.
