Problems solved by technology

[0021] This defect mainly concerns the physical deformation (even in millimeters) caused by the bearing pressure exerted by the vent valve stopper on the bearing SS22
Such physical deformations are usually imposed on at least a portion of the joint profile JC2, and this negatively interferes with the integrity of the seal existing between the cylinder head and the head / compression chamber of the alternating compressor; after all, these physical deformations Ultimately creates an escape point for the working fluid which is unacceptable and / or undesirable in most alternative compressors

Embodiment Construction

[0035] According to the concept and purpose of the present invention, it discloses a cylinder head, the area of ​​the support / housing of the cylinder head for the discharge valve stopper is capable of detached and elastic mechanical deformation, which deformation does not Does not extend (or at least strongly reduces) to the sealing area between the compressor cavity and the discharge chamber of the alternating compressor.

[0036] This will enable maintaining the integrity of the seal between the compressor and the head / compression chamber of the alternating compressor for that area.

[0037] Basically, said protrusions are able to absorb deformations imposed by the pressure of the valve stopper assembly, so that the deformations are not transferred to the joint area, thereby contributing to the correct functionality of the joint area.

[0038] The cylinder head comprises a substantially rigid block 1 with a substantially square or circular periphery.

[0039] The block 1 ha...

Abstract

A cylinder cover for alternative compressor comprises a block (1) provided with at least a sealing contour (11) and at least a support projection (3) for supporting a discharge valve stop. Said support projection (3) is spaced from the sealing contour (11) through at least one gap (4).

Description

technical field [0001] The present invention relates to a cylinder head for an alternating compressor, and more particularly to a cylinder head comprising support and retention means for a discharge valve stop present In alternate compressor head assemblies. Background technique [0002] Compressors, including alternating compressors, are generally known as machines for increasing the pressure of any (usually gaseous) working fluid. [0003] In this respect, more particularly, alternating compressors are able to increase the pressure of the working fluid by controlled changes in the volume of the compression chambers, wherein this controlled change in volume is carried out by a piston capable of alternating displacement inside the compression chambers. [0004] Thus, the inherent function of an alternating compressor consists of two functional steps, namely a suction step and an evacuation step. [0005] A suction step is created when the piston (in the compression chamber...
