Embodiment 1

[0058] 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

[0060] 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

[0062] 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 an air cylinder, a cylinder cover, a piston and a pipeline. The air cylinder is connected with the cylinder cover, the piston is arranged in the air cylinder, the pipeline is connected with the cylinder cover, a seat port communicating the pipeline with the air cylinder is arranged on the cylinder cover and at the joint of the pipeline and the cylinder cover, a valve is arranged at and matched with the seat port, and the valve is controlled by the piston to open and close the seat port according to a timing relation. An air distribution system of the engine is simplified, and air distribution efficiency of the engine is improved.

Description

[0001] This application is a divisional application whose original application number is 2011100395962, the original application date is February 17, 2011, and the name is a direct-acting valve engine. technical field [0002] The invention relates to the field of thermal energy and power, in particular to a direct-acting valve engine. Background technique [0003] 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-...
