Abstract

The invention makes it possible to increase the efficiency and expand the field of application of a three-dimensional rotary machine by enabling operation in aggressive environments. Case 1 and rotor (P) 2 with portions of the toroidal surface are interconnected along one cylindrical surface with the formation of a toroidal working cylinder (Ts) 5. The piston with shaped cams is placed in Ts 5 and is fixed on case 1. The cams are located on both side of the piston. The spring-loaded contactors are installed in P 2 in the form of hollow cylindrical spools 8 located in radial bores 9 P 2 with the possibility of interaction with the piston and C 5.

Description

This invention relates to a hydromash making, in particular to rotary engines and compressors.

The purpose of the invention is to increase efficiency and expand the scope by providing opportunities to work on aggressive media.

Fig, 1 shows a machine, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 - kinematic connection of the load and the washer.

The hydraulic machine comprises a housing 1 and a rotor 2 with portions of a torus-like surface 3, mated to each other along one cylindrical surface 4 with the formation of a toroid-shaped working cylinder 5. On the housing 1 a piston 6 is fixed with profiled cams 7 located on both sides of the piston 6. In the rotor 1 spring-loaded locking devices are installed, made in the form of hollow cylindrical spools 8 located in the radial bores 9 of the rotor 2 with the ability to interact with the piston b and form in a toroid-shaped working cylinder 5 cavities of high and low pressure. In case 1 there is a switchgear, including supply channels 10 and outlet 11 of the working medium discharging into the cylinder 5 in the area of the cams 7. Each spool 8 is made multi-stage and installed in the bore 9 with the formation of three cavities isolated from one another. intermediate 13 and peripheral 14, while the latter (14) and intermediate 13 cavities are connected respectively with cavities of high and low pressure of cylinder 5 by means of bypass channels 15 and 16, made in the rotor 2 on both sides 8, and the springs 17 are located in sealed internal bores 18 of the spool 8. In the bore 18 of each spool 8 a washer 19 is installed, kinematically connected by a flexible link 20 with a load 21 placed in an additional bore 22 of the rotor 2. The load 21 can be preloaded by a spring 23 installed in the bore 22 of the rotor 2 or several springs {not shown), the rotor 2 is fixed on the shaft 24,

coaxially mounted in housing 1. The machine is equipped with seals 25.

The machine works as follows.

The working environment under pressure serves

through channel 10 into the toroid-shaped working cylinder 5, which, acting on the horshen 6 and the spool 8, causes the rotor 2 to rotate. The spent working medium is displaced from cylinder 5 to discharge channel 11. If necessary, reversing the working environment

is fed into channel 11, and discharged through channel 10. Installing 2 loads 21 in the rotor, kinematically connected to washers 19 by flexible connection 20, results in a more balanced pressing of spools 8 to cylinder 5, which increases the efficiency of the machine as a whole and also allows It does not pump over aggressive and viscous working media.
