DIAMETRAL VOLUME MACHINE (VERSIONS) Russian patent published in 2012 - IPC F04C2/344 F04C18/344 F01C1/344 

FIELD: machine building.

SUBSTANCE: diametral volume machine comprises a casing 1, the following components arranged inside its cylindrical cavity 4 - a rotor made in the form of an end cylindrical faceplate, a guide cylinder 6, installed as capable of rotation and with eccentricity relative to the faceplate axis and having open diametral channels 7 with end holes 8 on the end surface from the faceplate side, and working elements 9, installed on the faceplate as capable of displacement in the channels 7 during its rotation. In the cavity 4 in the area of an inlet 2 and an outlet 3 channels there is an inlet cavity 10 and an outlet cavity 11, which are not connected to each other, a cylinder 6 is made with an outer diameter equal to the diameter of the cavity 4, and has end holes in each channel 7, which correspond to the cross section of the channel 7, or end walls 12 with holes. End surfaces of the cavity 4 of the casing 1, the faceplate and the cylinder 6 are on contact and form working chambers with end holes in channels 7 for inlet and outlet of a working fluid. Elements 9 are fixed on the faceplate 5 and are made in the form of a finger or a bushing installed on the finger as capable of rotation, or a plunger installed on the finger as capable of rotation around the centre of its longitudinal axis. The element 9 has a slid fit in the channel 7. The length of the element 9 travel is limited with the length of the appropriate channel 7.

EFFECT: development of a diametral volume machine having high efficiency of working fluid pumping at high pressures and wide area of application.
