ROTARY MACHINE (VERSIONS), WORKING MEMBER FOR ROTARY MACHINE AND PLANT USING SUCH MACHINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; rotary internal combustion engines.

SUBSTANCE: proposed machine has housing accommodating rotor. Inner surface of housing has form of two intersecting parts of cylinders of different diameters with parallel axes. Rotor installed in housing coaxially to smaller diameter cylinder consists of at least two sectional segment parts on which ring-shaped rotor covers are installed and at least two pairs of ring members connected in pairs and installed for turning relative to segment parts of rotor. Machine is furnished with hinged members arranged between ring members of each pair, working member whose axis of rotation coincides with axis of larger diameter cylinder and which is arranged in holes of hinge of hinge members for travel and contacting by working surface at rotation with inner working surfaces of sectional segment parts of rotor, covers of rotor and inner end face and cylindrical surfaces of housing to form variable-volume inner working chambers between sectional segment parts of rotor and working member, and variable-volume outer working chambers between working members, inner surfaces of housing and outer surfaces of rotor. According to second version, each pair of members in rotary machine consisting segment member and ring member is made for travel along ring guides of other pair. Working member of rotary machine has housing in which communicating inner chambers are made in each part arranged between its axis of rotation and each working surface designed for contact with inner cylindrical surface of housing. One of communicating inner chambers is working combustion chamber, and second chamber is designed for filling with working medium for subsequent scavenging of working chamber and it is made for injection of fuel mixture into said chamber and discharge of combustion products into main working chamber of rotary machine. Engine plant has one first rotary machine operating as pump and second rotary machine operating as engine. Outlet of each first rotary machine is connected with at least one working chamber of each second rotary machine, either directly or through receiver. Invention makes it possible to create rotary machine with universal kinematic which can be used as internal combustion engine and pump and to simplify design of machine, reduced material usage, increase manufacturability and reduced its cost at other similar conditions owing to use of less complex and expensive processes of manufacture.

EFFECT: reduced materials usage, improved manufacturability, simplified design.
