Benefits of technology

"The present invention relates to a reciprocating compressor with mounting leg parts that are designed to absorb deformation during the tightening process of the compressor. The mounting leg parts are made with a connecting portion and a projected portion that has a lower level of rigidity compared to the connecting portion. This allows the deformation occurring during the tightening process to be concentrated at the projected portions, reducing the extent to which the tightening pressure is transmitted to the cylinders via the connecting portions. This design helps to keep the cylinder deformation within the allowable range."

Problems solved by technology

Accordingly, as the mounting leg parts disposed at the cylinder block are fastened onto the mounting positions with mounting bolts or the like to install the compressor at the installation location, the tightening pressure occurring as the mounting bolts are tightened causes deformation of the mounting leg parts, but since the projected portions formed at the mounting leg parts are formed to have a relatively low level of rigidity compared to the connecting portions, the deformation occurring during the tightening process manifests in a concentrated manner at the projected portions.

Embodiment Construction

[0020] The following is an explanation of embodiments of the present invention, given in reference to the drawings. A reciprocating compressor 1 shown in FIGS. 1 through 3, which is used in a refrigerating cycle with a coolant used as a working fluid, comprises a front-side cylinder block 2, a rear-side cylinder block 3 mounted at the front-side cylinder block 2, a front-side cylinder head 5 mounted at the front side (the left side in FIGS. 1 and 2) of the front-side cylinder block 2 via a valve plate 4 and a rear-side cylinder head 7 mounted at the rear side (the right side in FIGS. 1 and 2) of the rear-side cylinder block 3 via a valve plate 6. The front-side cylinder head 5, the front-side cylinder block 2, the rear-side cylinder block 3, and the rear-side cylinder head 7 are fastened together along the axial direction with a tightening bolt (not shown) and constitute the housing for the whole compressor.

Abstract

A reciprocating compressor comprising a cylinder block (3) having formed therein a plurality of cylinders (11), a shaft rotatably passing through the cylinder block and pistons engaged in reciprocating movement inside the cylinders (11) as the shaft rotates, which is installed by fastening mounting leg parts (31) disposed at the cylinder block (3) at mounting positions, is characterized in that the mounting leg parts are each constituted with a connecting portion (31a) extending from the cylinder block 3 and a projected portion (31b) formed continuously to the connecting portion to project on one side or both sides of the connecting portion along the tightening direction and that the projected portion (31b) has a lower level of rigidity compared to the connecting portion (31a). The reciprocating compressor eliminates the need for rigorous management of the piston clearance by assuring firm installation via the mounting leg parts and also assuring smooth movement of the pistons with the extent of cylinder deformation kept within the allowable range.

Description

TECHNICAL FIELD [0001] The present invention relates to a reciprocating compressor which is installed by fastening mounting leg parts of the cylinder block at specific positions with mounting bolts or the like. BACKGROUND ART [0002] A reciprocating compressor includes a cylinder block having a plurality of cylinders formed therein, a shaft rotatably disposed so as to pass through the cylinder block and pistons engaged in reciprocating movement inside the cylinders as the shaft rotates. It is installed at a specific location such as an engine compartment by fastening and locking mounting leg parts formed at the external circumferential surface of the cylinder block or the like at specific positions with mounting bolts or the like. [0003] While the mounting leg parts formed at the cylinder block or the like may assume any of various structures, it is essential that they be firmly locked at the mounting positions. For this reason, in the structure disclosed in Japanese Unexamined Utili...
