Embodiment 1

[0027] This embodiment discloses a differential rotary sector piston combination, which is different from figure 1 In the traditional Kalts differential engine structure shown, the piston combination disclosed in Embodiment 1 includes a piston combination A and a piston combination B, such as figure 2 and image 3 shown. Both piston combination A 2 and piston combination B 1 include a fan-shaped part and a mandrel part, the fan-shaped part and the mandrel part are coaxial, the transverse section of the fan-shaped part is fan-shaped, and the longitudinal section of the fan-shaped part is rectangular. B1 coaxial suit, characterized in that the mandrel part of the piston combination A2 is a segmented hollow straight shaft 21, the mandrel part of the piston combination B is a stepped shaft 11, and the fan-shaped part 22 of the piston combination A2 and the piston combination The fan-shaped part 12 of B1 is a hollow structure, the inner diameter position of the fan-shaped part 2...

Embodiment 2

[0037] Most of the technical features of this embodiment are the same as those described in Embodiment 1. The difference is that the gas sealing device provided on the inner circular arc surface of the piston combination armor 2 fan-shaped part 22 of this embodiment is a tightly sealed honeycomb structure, such as Figure 7 As shown, the sealed honeycomb here is in the form of an insert, which is inserted into the cavity of the fan-shaped part 22 of the piston assembly A 2 along the axial direction.

Abstract

The invention discloses a differential rotation sector-shaped piston assembly. The differential rotation sector-shaped piston assembly comprises a first piston assembly and a second piston assembly, the two piston assemblies each comprise a sector-shaped portion and a mandrel portion, the sector-shaped portions and the mandrel portions are coaxial, and the first piston assembly and the second piston assembly are coaxially sleeved and arranged in a staggered mode. The differential rotation sector-shaped piston assembly is characterized in that the mandrel portion of the first piston assembly is a segmented hollow straight shaft, the mandrel portion of the second piston assembly is a stepped shaft, the sector-shaped portion of the first piston assembly and the sector-shaped portion of the second piston assembly are each of a hollow structure, and axial mortises are formed in the inner diameter position of the sector-shaped portion of the first piston assembly and the inner diameter position of the sector-shaped portion of the second piston assembly; and axial tenons are arranged at the corresponding positions of the mandrel portion of the first piston assembly and the mandrel portion of the second piston assembly, and the sector-shaped portions and the mandrel portions are connected through the axial tenons and the axial mortises. Compared with an existing structure, the structural rigidity is improved through the structure and the connecting mode, enough machining space is provided for an internal liquid cooling channel, and the problems of vibration, heat dissipation and lubrication can be solved.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a differential rotary sector piston combination and a rotary piston engine. Background technique [0002] The rotary piston engine described in the present invention can be regarded as belonging to Katz differential engine. This differential engine is a special engine. In this kind of engine, the high-pressure gas after ignition (compression ignition) directly pushes the piston to accelerate the rotation, so the connecting rod crank mechanism and the intake and exhaust valve mechanism are omitted, and the force on the parts is small, so the whole machine has small volume and weight. Light features, especially suitable for the aviation industry. Ma Xiangping of the Academy of Armored Force Engineering in China and Professor Pan Cunyun of the National University of Defense Technology have researched this, but so far no reports of practical application have been seen.
