Embodiment 1

[0057] like figure 1 The shown direct-acting valve engine includes a cylinder 1, a cylinder head 2, a piston 3 and a pipeline 4, the cylinder 1 is connected to the cylinder head 2, the piston 3 is arranged in the cylinder 1, and the pipeline 4 Connected with the cylinder head 2, the connection between the pipeline 4 and the cylinder head 2 is provided on the cylinder head 2 to communicate with the pipeline 4 and the cylinder 1. A valve body 7 is arranged there, and the valve body 7 cooperates with the seat port 6, and the valve body 7 is controlled by the piston 3 to open and close the seat port 6 according to a timing relationship.

Embodiment 2

[0059] like figure 2 The difference between the shown direct-acting valve engine and Embodiment 1 is that the direct-acting valve engine also includes a high-pressure working medium source 8, and the seat port 6 is set as an outwardly opened seat port 601, and the high-pressure working medium source 8 communicates with the pipeline 4, and the high-pressure working medium in the high-pressure working medium source 8 is quantitatively introduced into the cylinder 1 through the outer opening 601 according to the timing relationship, no longer undergoes combustion chemical reaction, and directly expands to push the Described piston 3 works externally.

Embodiment 3

[0061] like image 3 The difference between the shown direct-acting valve engine and Embodiment 1 is that the direct-acting valve engine also includes a high-pressure source of working fluid 9, and the seat port 6 is set as an outwardly opened seat port 601. In the valve body 7 is provided with a closing elastic body 701, the high-pressure working medium source 9 is connected to the pipeline 4, and the high-pressure working medium in the high-pressure working medium source 9 is drawn by the outer opening 601 according to the timing relationship. Quantitatively introduced into the cylinder 1, after the combustion chemical reaction, the piston 3 expands to push the piston 3 to do work.

Abstract

The invention discloses a direct-acting valve engine which comprises a cylinder, a cylinder cover, a piston and a pipeline, wherein the cylinder is connected with the cylinder cover; the piston is arranged in the cylinder; the pipeline is connected with the cylinder cover; the cylinder cover is provided with a seat hole used for communicating the pipeline and the cylinder at the connecting part of the pipeline and the cylinder cover; a valve body is arranged at the seat hole; the valve body is matched with the seat hole; and the valve body is controlled by the piston for opening and closing the seat hole according to the timing relationship. The direct-acting valve engine simplifies a gas distribution system of the engine and improves the gas distribution efficiency of the engine.

Description

technical field [0001] The invention relates to the field of thermal energy and power, in particular to a direct-acting valve engine. Background technique [0002] There are basically two types of traditional gas distribution methods for engines, one is the cam control method, and the other is the gas distribution method with openings on the side wall of the cylinder. The former mechanism is complicated, and the latter causes pollution due to leakage of lubricating oil. If it is possible to find another gas distribution method or a method of introducing working fluid or original working fluid to the cylinder and a way of exporting exhaust gas, the engine structure will be simplified. Especially for the engine that fills the cylinder with high-pressure working fluid or high-pressure original working fluid, a new gas import and export method is needed. Contents of the invention [0003] In order to solve the problems existing in the above-mentioned existing engine, the tec...
