Prevention of unpowered reverse rotation in compressors
InactiveUS20060222510A1prevent reversalrule out the possibilityFluid parameterOscillating piston enginesDrive motorAir conditioning
The shutdown of a compressor (10) installed in a refrigerant circuit (2) in air conditioning or refrigeration system is controlled so as to prevent unpowered reverse rotation of the compressor. Prior to terminating electric power to the compressor drive motor (24), the pressure within the system is relieved and substantially equalized across the compressor, thereby eliminating the possibility of unpowered reverse rotation of the compressor at shutdown. Pressure relief and equalization may be achieved by reducing the operating speed of the compressor to a low forward speed for a period of time prior to deenergizing the compressor drive motor. Pressure equalization may also be achieved by driving the compressor in reverse rotation prior to deenergizing the drive motor.

Self-cooled rotary engine and pump
ActiveUS12624656B1Oscillating piston enginesInternal combustion piston enginesRotary engineInternal combustion engine
A rotary combustion engine includes a cylindrical housing with a plurality of internal cavities. Each of the internal cavities is a cylindrical segment of the housing, and a plurality of stationary blades are attached to its inner wall. The stationary blades extend inward to ride along the surface of a central shaft, contacting the shaft with a seal. Each cavity contains a rotor blade attached to the shaft and configured to drive the shaft. Each rotor blade extends outwardly to an inner curve of the housing with a sealing means. Each of the plurality of rotor blades has a reciprocating circular motion inside each of the cavities along the shaft between each of the stationary blades, thereby generating rotational power, delivering compressed rotational force, and provides cooling for the cavity.

Low-speed large-torque water hydraulic motor suitable for deep sea mechanical arm
The invention discloses a deep sea water hydraulic mechanical arm low-speed large-torque motor which mainly comprises a motor body and a valve flow distribution mechanism, the motor body mainly comprises a crankshaft, a water lubrication bearing assembly, a plunger assembly, a swing cylinder, a shell, a front end cover and a rear end cover, and the valve flow distribution mechanism mainly comprises a valve frame, a valve set, an ejector rod and two cams. The valve frame is used for supporting and protecting internal components, the water-lubricated bearing component realizes full water lubrication when the motor works in a deep sea environment by adopting a bidirectional six-groove structural design, and the valve flow distribution mechanism replaces a traditional low-speed large-torque motor shaft flow distribution or disc flow distribution structure. The problems that a flow distribution mechanism is seriously abraded and short in service life when working for a long time in a marine environment are solved, and the problem that the flow distribution mechanism is prone to failure when driven by a high-pressure water medium is solved. The low-speed large-torque motor of the deep sea water hydraulic mechanical arm has the advantages of being simple in structure, stable in performance, high in power density and high in applicability.
