| abstract | The invention can be used in the design of piston drilling pumps. The purpose of the invention is to increase the durability of the cylinder-piston pair by improving heat transfer. A cylinder (C) 2 with a sealing element (CI) is installed in the cylinder (C) 1, in which the piston 4 with the driving rod 5 is housed to form the working chamber 3. The piston 4 is spring-loaded from the side of the rod 5 relative to C 1, it is made with an emphasis 7 and mounted with respect to C 1 and interacting with movements with piston 4 and support 7. A variable volume sealed chamber 8 communicates through an annular channel 9 formed by side surfaces C 1 and C 2 with chamber 3. The volume of chamber 8 is larger than the channel volume 9. C 1 and C 2 are stepped and set s in one another. The chamber 8 is formed between the ends of their steps or between the end surface of the C 1 and the UE. The UE is made in the form of a flexible ring, the peripheral parts of which are fixed on the end surfaces C 2 and C 1. The flexible ring is made in the form of a pre-compressed elastic element. The UE can be made in the form of a reinforced elastic element provided on the lateral peripheral surfaces with rigid rings installed tightly and stationary with respect to C 2 and C 1. The volume of the chamber 8 is larger than the internal volume of the channel 9 ensures that the fluid in the channel 9 is updated in each working cycle. 5 hp f-ly, 3 ill. |
