Abstract: This invention of a continuous motion revolving piston engine describes a machine comprising piston(s) fitted to rings that revolve around a stator circular base which has a cavity in which a disc fits to create a closed combustion compartment together with the casing. The disc has a disc cavity to allow the piston to pass. The rotation of the disc and piston are synchronized to allow the piston to pass through the disc cavity. As there are no reciprocating parts and optionally enables an oil free operation, it is more efficient and has cleaner exhaust than existing engines.

Abstract: The present invention relates to rotary screw positive displacement machines used as a vacuum pump wherein additional intake air is provided allowing cooling to the invention which permits extended operation at extreme vacuum pressure. The rotary screw nature of the vacuum pump allows operation without additional lubrication with the additional intake air ensuring that thermal expansion will not disrupt the tight tolerances of the invention. The invention allows simultaneous operation as a vacuum pump and air compressor.

Abstract: A hermetic scroll compressor has a scroll compressor section, a motor section and a hermetic casing which encases the compressor and motor sections. The space in the casing is divided into an upper chamber and a lower chamber by a frame by which a shaft interconnecting the compressor and motor sections is rotatably supported. The upper and lower chambers are communicated with each other through a communication passage which is formed in the outer periphery of the frame. The hermetic casing is composed of an upper section, a barrel section and a lower section which are welded together. The barrel section is formed by rolling a sheet into a cylindrical form and welding opposing ends of the rolled sheet so as to form a weld seam joint. The frame is fixed in the casing with the weld seam joint disposed within the circumferential width of the communication passage, so that the outer periphery of the frame is in tight contact with the inner periphery of the barrel section except for the portion where the communication passage is formed.

Abstract: In a scroll type compressor in which a compression mechanism compresses a gaseous fluid with moving the gaseous fluid along a spiral path to produce a compressed gas, an escaping path is provided for escaping the compressed gas from the compression mechanism at an intermediate portion of the spiral path. A pressure transmission path transmits pressure of the compressed gas to a valve mechanism which is for controlling an open and an close of the escaping path. The pressure transmission path has a delay mechanism for delaying transmission of a change of the pressure to the valve mechanism.

Abstract: A variable displacement type compressor is disclosed. The compressor includes a housing having fluid inlet and fluid outlet ports. A fixed scroll is fixed within the housing and has a circular end plate from which a first spiral element extends. The end plate of the fixed scroll partitions the inner chamber of the compressor housing into a front chamber connected to the fluid inlet port and a rear chamber. The rear chamber is divided into a discharge chamber connected to the fluid outlet port and an intermediate pressure chamber. The end plate of the fixed scroll has at least two holes which connect the fluid pockets to the intermediate pressure chamber. The end plate also has a communicating channel which connects the front chamber to the intermediate chamber. A control device controls the communication between the front chamber and intermediate pressure chamber. The control device is disposed on the intermediate pressure chamber, and a valve element of the control means is operated by pressure from the discharge chamber.
