Abstract

The invention relates to seal assembly for a rotary piston internal combustion engine comprising a rotating block (11) of a rotational shape with radially situated cylinders (12) with pistons (13) and an outer stationary case (10) with at least one intake port (14) and / or exhaust port (15). The outer surface (16) of the rotating block (11) is a rotational surface with a straight line or curved profile curve, on which transverse and / or side sealing parts, which are placed in the stationary case (10), sit. In circular side grooves (2) there is a side seal consisting of circular side sealing segments (1) that are always placed between neighbouring transverse sealing strips (3), which are placed in transverse grooves (4). Those sealing strips (3) go through the side grooves (2) across. In the place, where the side sealing segments (1) and transverse sealing strips (3) meet, there are joints (5) with notches (7) for inserting the side sealing segments (1) and transverse sealing strips (3)..

Description

technical field [0001] The present invention relates to an embodiment of a sealing device for an internal combustion engine comprising a rotating block exhibiting a rotatable shape and radially arranged cylinders with pistons. There is a fixed housing on the outside of the rotating block, which has at least one air inlet and / or air outlet. The cylinder rotary block and the stationary housing work together as a rotary valve. Background technique [0002] There are various engine designs today, in which there is a rotating block in a rotatable shape, radially provided with a cylinder with a piston, with an outer fixed housing and an intake and / or / exhaust port, where the cylinder rotates the block With this stationary housing it can act like a rotary valve. Common engines include two-stroke and four-stroke engines, which have two, three, and multiple cylinder configurations. Some engines have a crankshaft mechanism and others have other known mechanisms to transmit piston ac...
