Embodiment 1

[0076] Referring to Figures 6a-6e, in combination with Figures 4a-4e and Figure 5, the medium inlet and outlet part 8 of the present invention is in the shape of a straight wall cylinder, and the second medium suction port 8d and the second medium discharge port 8b are provided on the cylinder wall ; The second medium suction port 8d and the second medium discharge port 8b are completely identical in size, shape and orientation to the first medium suction port 1e and the first medium discharge port 1b on the housing 1 shown in FIGS. 4a to 4e. same. The inlet and outlet parts 8 of the present invention are installed in the inner cavity of the housing 1 according to the corresponding circumferential orientation, and the second medium suction port 8d and the second medium discharge port 8b on it just meet the working chambers of the cylinders on the fluid machine cylinder 2. 2b media suction and discharge use requirements.

[0077]Referring to Figures 7a-7e, combined with Figure...

Embodiment 2

[0080] Referring to Figures 9a-9b, combined with Figures 4a-4e, the only difference between the two shell structure schemes is that the first medium suction port 1e on the shell 1 of this embodiment is a large octagonal-like hole, and the octagonal-like The large holes correspond to the two adjacent cylinder working chambers 2b on the cylinder body 2 at the same time. In fact, it is equivalent to connecting the two isosceles trapezoidal first medium suction ports 1e corresponding to the two cylinder working chambers 2b on the cylinder body 2 respectively on the housing 1 shown in Fig. The machining of the first medium suction opening 1e of the body 1 can be suitably simplified.

[0081] Referring to Figures 10a-10b, in combination with Figures 6a-6e and Figures 9a-9b, the second medium suction port 8d and the second medium discharge port 8b on the inlet and outlet parts 8 of this embodiment are the same as those of the housing 1 shown in Figures 9a-9b. The first medium suctio...

Embodiment 3

[0084] refer to Figures 12a-12b , combined with Figures 4a to 4e, the only difference between the two housing structures is that the first medium suction port 1e on the housing 1 of this embodiment is four symmetrically arranged right-angled trapezoidal holes, which are located at the same length of the inlet and outlet parts 8 The two right-angle trapezoidal second suction ports on the section correspond to the same cylinder working chamber 2b on the cylinder block 2 . The long bases of the two pairs of right-angled trapezoidal holes are adjacent and parallel, perpendicular to the generatrix of the cylinder wall of the inlet and outlet part 8, and tangent to or adjacent to the corresponding cylinder hole 2b on the cylinder body 2. In fact, it is equivalent to dividing the two isosceles trapezoidal first suction ports on the housing 1 shown in Fig. 8. Each part of the opening area on the cylinder wall is not large, which helps to ensure that the rigidity of the cylinder body...

Abstract

The invention relates to the compression mechanical field and provides a calor fluid machine which comprises a shell body and a cylinder body; a first medium suction port and a first medium discharge port; the calor fluid machine is characterized in that a straight-wall cylindrical medium inlet-outlet part is arranged in the shell body; the external cylindrical surface of the cylinder body of the medium inlet-outlet part is tightly matched with the inner cylindrical surface of the shell body; the inner cylindrical surface of the cylinder body of the medium inlet-outlet part is matched with the external cylindrical surface in a sliding way; a second medium suction port and a second medium discharge port are arranged on the cylinder wall of the medium inlet-outlet part corresponding to the cylinder operation cavity, and are communicated with the first medium suction port and the first medium discharge port arranged on the shell body. The calor fluid machine has the advantages of simplifying the shell structure, improving the machining efficiency and the machining accuracy of the cylinder operation cavity medium inlet-outlet, maintaining the fluid machine rapidly and saving the maintenance cost through replacing the medium inlet-outlet part, facilitating the product model extension and the production organization.

Description

technical field [0001] The invention relates to the field of compression machinery, in particular to a Carroll fluid machine. Background technique [0002] The article "Compressor Uses New Rotary Principle [Document 1]" in the fourth issue of the Canadian magazine "Design Engineering" published in 1973 introduced a new type of compressor for the first time in the world. This new type of compressor was developed by Robert who graduated from Oxford University. Karol proposed it, and it was further developed by Richard Ansdale, a famous British rotating machinery expert, and a prototype was manufactured by the British Well-worthy company. This new type of compressor is mainly composed of a rotating cylinder block with a spherical outer peripheral surface, a matching shell with a spherical inner surface that can be split up and down, two cylindrical pistons with spherical end faces, and a cylinder with two The main shaft of an eccentric wheel, and the end covers and bearings on...
