• Device represents a device with six gears 10 and one gear 10a, six double-sided working rotary pistons A (double sided working rotary piston A consists of the body 6 with a hole in the centre and two (working) protrusions A) and one hexagonal auxiliary rotary piston G (hexagonal auxiliary rotary piston G consists of the body 6 which has a hole in the centre and six (auxiliary) shaped recesses G arranged each from other at the angles of 60 degrees) and can be best used as a vacuum pump, compressor, pump, consists of the piston housing 11 , gear housing 9, separating wall 7 the front cover 12 with a hole for the shaft 4 and the rear cover 1 with inlet-outlet connections 20, connected to each other by bolts 16 that go through the appropriate holes and are screwed in the body of the rear housing 1 , in the piston housing 11 are set six double-sided working rotary pistons A arranged each from other at 60 degrees while in the centre of the housing 11 there is one hexagonal
• the external shape of the device can be round or of different thereto appropriate shape.
• Device cah be used wherever there is a need to pump the fluid, to achieve pressure or vacuum; device can be directly driven by any type of the motors it can be fitted therein or be connected withthe motors by means of indirect connection and such are cardanshafts, electromagnetic lamellas, pulleys and in all other existing and thereto appropriate modes.
• Length (thickness) of the pistons and the length of the housing can be increased or decreased (proportionally). Sealing of the contact surfaces between the elements of the assembly can be done in all known and therefore appropriate modes.
• This device can have (working) protrusions, of any of the mentioned shapes; A; B; C; D; E or F and according to these the choice of the auxiliary shaped recesses G or H is made.
• Device represented in figures 129 to 137 represents a device with a pair of gears, one single-sided working rotary piston A (single-sided working rotary piston A consists of a body 6 with a hole for the shaft in the centre and one (working) protrusion A) and one single-sided auxiliary rotary piston G (single-sided auxiliary rotary piston G consists of the body 6 with a hole for the shaft in the centre and one (auxiliary) protrusion G) and is best used with internal combustion engines, it consists from the piston housing 11 with inlet-outlet connections 20, then the gear housing 9, the separating wall 7, the front cover 12 and the rear cover 1 , that are each to other coupled by bolts 16 that go through the appropriate holes 16x and are screwed in the body of the rear cover 1 , and the piston housing 11 there is set one-sided working rotary piston A and one single-sided auxiliary rotary piston G that over the shafts 4 and 5 are firmly connected to the gears 10 in the gear housing 9, where the piston housing 11
• the external shape of the device can be round, elliptic... etc. device can be used a part of a motor i.e. wherever there is a need to use it.
• Inlet - outlet connections 20 can be in the piston housing 11 or at the rear cover 1 of that housing or combined where the inlet is in the housing and outlet in the cover and vice versa.
• Length (thickness) of the pistons and the length of the housing can be increased or decreased (proportionally), all the single-sided pistons can be balanced in all the known and thereto appropriate modes, to prevent them to bring about vibrations in the working process. Sealing of the contact surfaces between the elements of the assembly can be achieved in all existing and thereto suitable modes.
• This device can be with working protrusions of any of the mentioned shapes; A; B; C; D; E or F and according to which the choice of the (auxiliary) shaped recesses G or H, is made.
• This type of the device can be used as a compressor, a pump, a vacuum apparathus, and therein can be, instead of one working and one auxiliary; double-sided working and double-sided auxiliary, or three-sided working and thee-sided auxiliary, or four-sided working and four-sided auxiliary rotary pistons.
