TWO-AXIS MACHINE (VERSIONS) Russian patent published in 2017 - IPC F01C1/344 F01C3/06 

FIELD: transportation.

SUBSTANCE: according to the first version, a two-axis machine comprises the outer and the inner contours 1 and 2 of rotation bodies and at least one locking element 3. The contour 2 is located in the contour 1 with the possibility of its rotation relative to the contour 1, and between them a working cavity is formed, in which the inlet 5 and the outlet 6 are formed. The element 3 is installed in the contour 2 with the possibility to move relative thereto and to the contour 1. The axes of the contours 1 and 2 are arranged non-coaxially. The symmetry centres of the contours 1 and 2 are displaced relative to each other. The element 3 divides the working cavity into high and low pressure zones and is made with the possibility to move the working body from the inlet 5 to the outlet 6 as the contour 2 rotates. Between the surface of the contour 2 and a part of the surface of the contour 1, a seal seat 11 is formed, consisting of a spiral surface and two surfaces, spaced in 180 degrees, located in the contour 1.

EFFECT: increasing working volume while reducing weight and size.
