  • Suction arrangement for a refrigeration compressor
    Patent number: 8992186
    Abstract: A refrigeration compressor is provided and may include a shell carrying a suction-inlet tube having an outlet nozzle opened to the interior of the shell and a cylinder block to which is mounted a suction muffler that incorporates an admission tube provided with an inlet nozzle. The inlet nozzle of the admission tube may be disposed adjacent to the outlet nozzle of the suction-inlet tube. The inlet nozzle may admit under at least one of the conditions of underpressure in its interior or deflection of the refrigerant-fluid flow in the interior of the shell the gaseous phase and may direct the liquid phase to a region of the shell external to the inlet nozzle.

  • Electrical power generation from reciprocating motion of floats caused by waves
    Patent number: 7956479
    Abstract: An apparatus, system and method for generating electricity by using the reciprocating motion of floats caused by waves includes a plurality of cylindrical floats each traveling on a cylinder push rod. The wave motion through the floats forces hydraulic fluid in a closed loop hydraulic system into a hydraulic motor, and converts the kinetic energy of the linear float motion to rotary motion to drive electrical generators.

  • Terminal assembly for hermetic compressor
    Patent number: 5584716
    Abstract: A hermetic terminal assembly has a plurality of conductor pins which define integral fusible links (36). A unique plug is provided which both separates the individual wires (70) leading to the conductor pins and allows, in cooperation with a fence or with the shell (21) of the compressor (10), for the restriction of access to the conductor pins while the conductor pins are connected to a power source. This unique plug also allows for the positioning of the integral fusible link on the outside of the shell (12) thus resolving the problems associated with compromising the integrity of the shell (12) upon separating of the fuse-like link (36). In addition, the plug insures that the conductor pins are maintained in an electrical isolated fashion should the fuse-like link (36) separate. The fence can be formed as a separate member or alternately to be integral with the terminal body.
