摘要： A work machine that can discharge water collected inside a casing to the outside, reduce leakage of noise, and reduce entry of foreign matter from outside. The work machine includes a bottom portion cover forming a portion of a casing, and the bottom portion cover includes: at least two ribs and a bead (strengthening structure portions) that are formed substantially perpendicular to a bottom surface of the bottom portion cover; and a drain hole located in a connecting portion connecting the bottom surface of the bottom portion cover and a water-discharging rib among the at least two ribs. An upper portion of the water-discharging rib is located over the drain hole.

摘要： A rotary pump is provided for fluid transfer. The pump includes a planar housing, an elongated rotor, a pair of double-concave blades, fore and aft cover plates, and a gear box. The housing has a circular center cavity, and a pair of circular lateral cavities overlapping the center cavity and disposed along a longitudinal axis. The rotor is disposed on a rotor shaft along a rotation axis perpendicular to the longitudinal axis within the center cavity. The blades flank the rotor and are disposed within their corresponding lateral cavity and turn on corresponding blade shafts parallel to the rotor shaft. The fore and aft cover plates flank the housing along the rotation axis to cover the center and lateral cavities. The blades turn opposite from the rotor.

摘要： A rotary combustion engine, such as a Wankel engine has a rotor with a rotor pocket for receiving air-fuel mixture that is combusted therein to propel the rotor within the housing. Rotor air channels extend from an inlet that is configured in the compression chamber to an outlet configured in the rotor pocket to deliver compressed air-fuel mixture to said rotor pocket. The rotor air channels have an open portion, open on the face of the rotor and a closed portion extending as a conduit into the rotor to the rotor pocket. Fuel may be delivered to the rotor air channel from a rotor-gear fuel conduit that receives fuel from the fixed gear or a side-wall fuel conduit that receives fuel from a housing side-wall injector through a side-wall fuel transfer port. Rotor air channels may be configured to direct air-fuel streams to intercept one another to enhance combustion.

摘要： A rotary engine includes a shroud surrounding a rotor. The rotor carries a combustion chamber spaced from an axis of rotation of the rotor. A pressure activated valve is located between the combustion chamber and obliquely arranged exhaust nozzles. An ECU controls the combustion cycle of the engine based on a signal from a pressure sensor in the combustion chamber. The electronic control responds to the pressure signal from the pressure sensor to open a fuel control valve, to fire a spark plug and cause combustion of the fuel within the combustion chamber, and to thereafter open an air control valve to purge the combustion chamber of exhaust gasses.

摘要： The Rotary Roller Motor (RRM) is a four cycle rotary internal combustion engine that uniquely overcomes many of the drawbacks of other rotary type engines, by having the Rotor ‘roll’ around the inside of the engine block, rather than scraping it. This is accomplished with a two part rotor. The inner part of the rotor is composed of a Rotor Shaft (RS-12) with an Offset Circular Lobe (OCL-11) rigidly attached to it. The Outer Rotor (OR-9) fits symmetrically around the Offset Circular Lobe, with Inter Rotor Bearings (IRB-10) between the two to allow free movement. The four cycles are separated by two barriers; the Compression/Power Barrier (CPB-13), and the Exhaust/Intake Barrier (EIB-6). Compression is controlled by two non-reversing barriers, the Non-reversing Compression Barrier (NCB-3) and the Compression Hold Barrier (CHB-14), on either side of the Combustion Chamber (CC-2).

摘要： An internal combustion engine comprises a plurality of engine units (50A-50C), each having a working space (11), in which two rotary pistons (20, 30) are arranged so as mesh with each other and thereby divide the working space (11) into an inflow region (12) and an outflow region (13). Each engine unit comprises a closable inlet opening (62A-62C) to the inflow region (12) and a closable exhaust gas outlet opening (64A-64C). The internal combustion engine further comprises a feed-line pipe (60) to the inlet openings (62A-62C) and an exhaust gas collection pipe (66) connected to the exhaust gas outlet openings (64A-64C), so that the engine units (50A-50C) are connected in parallel with each other. The internal combustion engine further comprises exhaust gas lines (63A, 63B) which connect the engine units (50A, 50B) with each other in series. In dependence upon a desired power output, a control device (70) operates some of the engine units (50B, 50C) either as internal combustion engines, wherein the respective inlet opening (62B-62C) is opened, or as expansion engines, wherein respective inlet opening (62B-62C) remains closed and the respective rotary pistons (20, 30) are instead driven by exhaust gas flowing in via the respective exhaust gas line (63A, 63B).

摘要： This patent discloses thrust vectoring ignition chamber engine. Thrust vectoring ignition chamber used in this engine is an annular cylinder having nozzles mounted in a way such that during fuel suction phase they are sealed and during ignition of fuel they are unsealed so that hot jets of ignited fuel escaping through nozzles cause coupled rotatory motion on the ignition chamber. Engine uses cam operated two transverse piston based mechanism for suction and compression of fuel which facilitates separation of fuel valve from ignition chamber with the help of which combustion process and suction-compression process can occur simultaneously. Flywheel mounted on extension of ignition chamber functions as output of the engine. Each half rotation of flywheel completes three phases namely fuel/air suction, compression and combustion. Thus this engine fires for every half revolution and therefore can give improved power boost.

摘要： A rotary engine casing having at least one end wall of an internal cavity for a rotor including a seal-engaging plate sealingly engaging the peripheral wall to partially seal the internal cavity and a member mounted adjacent the seal-engaging plate outside of the internal cavity. The member and seal-engaging plate having abutting mating surfaces which cooperate to define between them at least one fluid cavity communicating with a source of liquid coolant. When the casing includes a plurality of rotor housings, the end wall may be between rotor housings. A method of manufacturing a rotary engine casing is also discussed.
