POSITIVE DISPLACEMENT ROTARY MACHINE WITH SCREW CONICAL ROTORS Russian patent published in 2023 - IPC F01C1/16 F03C2/08 F04C2/16 F04C18/16 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the rotary machine. The rotary machine contains two conical screw rotors with intersecting axes. The rotors are located in conical borings (3, 4) of the housing. The axes of the borings (3, 4) coincide with the axes of the rotors. One rotor is divided along its length into sections (1.1, 1.2 and 1.3), the other into sections (2.1, 2.2 and 2.3). Sections (1.1, 1.2 and 1.3) are connected to each other by a common shaft (7), sections (2.1, 2.2 and 2.3) - by a common shaft (8). The sections are separated by fixed partitions (9, 10), hermetically sealed in the body. Partitions (9, 10) with the ends of the sections form a minimum gap that guarantees free rotation of the sections. The partition (9) is made with a closed groove (22) on the side surface, and the partition (10) is made with a groove (23). The body is made of two halves (5, 6), which are connected to each other in the plane of the axes of the borings (3, 4), and therefore the rotors. Inside half (5) there are recesses (24, 25), inside half (6) there are recesses (27, 28). The recesses (24, 25) are shifted along the axis relative to the recesses (27, 28).

EFFECT: creating a screw rotor machine with minimal leakage between the rotors, between the rotors and the housing.
