Description

The utility model relates to mechanical engineering, in particular to vane internal combustion engines, and can be used to create positive displacement pumps and compressors.

Known piston machine (Germany patent No. WO 2010/010094 A2 "Piston machine" IPC F01C 9/00 (2006.01)), containing a housing with a working chamber, which houses the bladed working body, shank, crank shaft.

The disadvantages of this piston machine are the low reliability of the mechanism due to the high specific loading of the main parts, which provide the transformation of the movement of the bladed working body into the rotation of the crank shaft (in particular, the crank-rocker pair), unsatisfactory specific weight and size and, as a result, low energy performance.

These shortcomings are due to the design of the piston machine and are determined by the features of its kinematic scheme.

Known piston machine (US patent No. US 2013/0205990 A1 "Piston machine" IPC F01B 3/00 (2006.01)), containing a housing with at least one working chamber, in which (which) are placed bladed working bodies that can be performed along with shanks, crank shafts.

This piston machine, along with the disadvantages inherent in the piston engine according to patent WO 2010/010094 A2 (mentioned above), has a significant structural complexity due to the presence of a large number of parts with complex geometry and manufacturing technology.

These shortcomings of this piston machine are also due to its design and are determined by the features of the kinematic scheme.

The device closest to the claimed object is a vane engine (RF patent No. RU 2700108 C1 "Vane engine" F01C 9/00, F02B 53/00 (2006.01)), containing a housing with a working chamber and a blade placed in it, a shank, cranks.

The disadvantages of this engine are the increased complexity of the design, low layout and weight and size, non-optimal configuration of the blade of the working body in terms of strength, bending resistance and fatigue endurance, and, as a result of the above, insufficient energy characteristics and reliability. The disadvantages are due to the peculiarities of the kinematic scheme of the engine and its design.

The technical problem solved by the utility model is the need to improve the energy performance and reliability of the vane engine.

The technical result provided by the utility model is to improve the energy performance and reliability of the vane engine.

The technical result is achieved by the fact that in a vane motor containing a housing with a working chamber and a blade placed in it, a shank, driving and driven cranks, according to the utility model, the blades are made of trapezoidal shape in the amount of from two to six and are placed on the core, the shank is mounted on axis of the core with blades, and the driven crank is located within the projection of the body on a plane perpendicular to the axis of the core.

The essence of the utility model is illustrated by the drawing, which shows a diagram of a vane engine with a crank-rocker parallelogram converting mechanism.

A vane engine with a crank-scotch parallelogram converting mechanism comprises a housing 1 with working chambers 2, in which a core 3 with blades 4 is placed, each of which (blades) divides each of the working chambers into two working volumes A and B. On the shank 5 of the core is hinged a slider 6 is installed, placed in the longitudinal groove 7 of the wings 8. The wings are pivotally connected to the cranks 9 (driven) and 10 (leading) installed in the housing. The cranks are also interconnected by a gear wheel 11.

A vane engine with a crank-scotch parallelogram converting mechanism operates as follows: the processes of the working cycle of the internal combustion engine are carried out in each of the working chambers 2 alternately in the working volumes A and B, as a result of which the core 3 with the blades 4 performs a cyclic angular movement (that is, an oscillatory movement) between its extreme positions, due to which the slider 6, mounted on the shank 5, interacting with the link 8 through the longitudinal groove 7, induces the link, forming together with the cranks 9 and 10 and the engine housing a parallelogram four-link mechanism, to bring the cranks into in-phase rotation, in this case, the torque can be removed from the shaft of any of the cranks, and the uniformity of the angular velocity of rotation of the cranks is ensured by the flywheel masses of the engine.

Thus, the use of a crank-rocker parallelogram converting mechanism makes it possible to improve the energy characteristics and reliability of the vane engine.
