Description

one

The invention relates to engine-building, in particular to rotor cooling systems for rotary-piston engines.

A liquid cooling system is known for a polygonal rotor of an internal combustion engine comprising arcuate channels formed on the sides of the rotor and interconnected via radial pipes, inlet and outlet channels connected through openings with arcuate channels, an annular groove made around the eccentric shaft and communicated with the channels intake, n throttling elements. In the known cooling system, the inertial forces acting on the cooling fluid in the arcuate channels connected to the inlet and outlet channels of the lateral sides of the rotor are mutually equal and do not contribute to the movement of fluid through the channels, and the zones of the arcuate channels from the rotor to the inlet and outlet channels located forward in the direction of rotation of the piston, are not filled with coolant due to the fact that the arcuate channels on the inner surfaces of one side are not connected to the arcuate channels of the other side porshn.

The purpose of the invention is to increase the cooling efficiency.

This goal is achieved by the fact that in the known system of liquid cooling a polygonal rotor of an internal c opan containing an arc-shaped engine. Channels made on the sides of the rotor and interconnected through radial pipes, inlet and outlet channels connected through holes to arcuate channels, annular groove made around the eccentric of the shaft and connected to the inlet channels and throttling elements, the latter are installed in arcuate channels in front of the hole mi inlet and after the outlet holes in the direction of rotation of the rotor.

FIG. I depicts a rotor with partial cuts, general view; in FIG. 2 a section A-A in FIG. one. .

The liquid cooling system of the polygonal rotor 1, which is hingedly connected to the shaft 2 by means of a bearing 3 fixed on the eccentric 4, contains an axial channel 5 and a radial hole 6 of the shaft 2, an annular groove 7 formed around the eccentric 4, inlet channels 8, arc-shaped channels 9 and 10 with throttling elements 1 and 12, radial pipes 13 and channels 14 of release. The cross-sectional areas of the arcuate channels 9 and 10 at the locations of the throttling elements П-н 12 are smaller than the cross-sectional areas of the radial pipes 13 running along the rotor tops and the channels 8 and 14, respectively. but intake and exhaust. The rotor has grooves 15 and 16 for

5 sets the seals, and the gear 17 is designed to implement a kinematic connection with the fixed gear of the engine side frame (not shown). The direction of rotation of the shaft is indicated by an arrow, and the circulation of coolant through the channels is indicated by wavy arrows.

When the engine is running, the cooling oil from the axial channel 5 of the shaft 2 flows into the annular groove 7 of the piston 1 through the radial

5, the opening 6 and, due to inertial forces, enters the channels 8, and then into the arcuate channels 9, where a smaller part of the oil flows through the zones of presence of the throttling elements 11 and is mixed with the oil coming out of the channels 8, and most of

0, the oil passes through the radial pipes 13 and enters the arcuate channels 10, in which a smaller part of the oil flows through the zones of the throttling elements 12 and mixes with the oil coming out of the radial pipes 3.

The main part of the oil is squeezed out through the exhaust ports 14 from the piston 1.

Constructive implementation of channels with different cross-sectional areas allows maximum use of inertial forces to move fluid in the channels and cool all areas of the piston.

The use of the invention will allow to create the required temperature conditions for the piston to increase the piston life and engine reliability.
