The structure is connected to each other by 2, but since there are many V-lease points in Xuansu's stomach and V-lease points with the outside air, KgILIIIKIIl'! The light that matches the theme, again,
Since the housing has a complex shape and is required to be lightweight, conventionally it has been made of aluminum casting, but the above-mentioned bulkhead part for the leprosy partition and the partition from the outside air are used. Since a certain peripheral part must have a large degree of rigidity necessary to prevent gas from blowing through due to deflection, it is an absolute requirement that the whole part be made thick. There were disadvantages such as an increase in rounded weight, an increase in external dimensions, and a high material cost.

The volumetric efficiency can be improved by reducing the amount of refrigerant gas that is distilled (by reducing the so-called top clearance). Note that when the valve plates 5 and 4 are fixed to the cylinder block 1.2 with the bolts 41 in this way, the valve plates 3 and 3 are
The bolt 41 also serves to position the valve plate 3.4.

有効である。Book 1! The example is something that has been developed as if it were a skill that has been improved.
Therefore, when the compressor is operated, refrigerant gas flows from the suction chamber 8 through the inlet hole 29 and the suction passage 28, and flows into the suction hole 3 of
5 into the V cylinder pore 50.31, and then discharged through the discharge hole 58 by the compression action of the piston 34 1F9.1! When the gas in the rear discharge w115 is press-fitted into the
It merges with the gas in the front discharge chamber 9 and flows out to the external circuit through the V cylinder pore 30.
Since the gas flow within 31 is unidirectional, the gas can be sucked in smoothly, which is effective in improving volumetric efficiency.

することができる。Now, in this compressor, the rear housing 6 has a structure in which only the discharge chamber 13 is formed and has no suction chamber.
It is only necessary to perform a V-rule on the joint surface with the V-
Since the tensile force caused by the tightening of the bolts 12 when connecting the rear housing 6 to the front housing 5 acts on the gasket 16, which is a cylinder material, through the stepped portion 14, the gasket 16 is strongly pressed against the end face of the cylinder block 2. A good '&v-ru' is ensured. In addition, the valve plate 4 itself is pressed at its shoulder edge by the stepped portion 14 of the rear housing 60, and is also held down by the central bulge 15 or attached to the cylinder block by the discharge valve mounting bolt 41. 2K11 is rather large, preventing the piston 54 from floating during compression and ensuring a seal with the end face of the Vψ cylinder block. Further K is both cylinder blocks 1゜2Th
! Since the rear housing 6 and the fourth plate 4 are covered with a ceramic housing 6 and the rear housing 6 is connected to the housing 5 in good condition, the only place where the outer air is connected is the connecting part. Therefore, the risk of gas leakage to the outside can be reduced.

量の軽減ならびに小型化を可能とするものである。In other words, the inner chamber 6 has only a discharge chamber 13 at its bottom, which eliminates the need for a partition wall that requires roundness and great rigidity to partition the space between the two parts, as in the case of the conventional art. It is sufficient to ensure sufficient strength to withstand tensile charges, so it is possible to fabricate the entire structure by pressing a thin steel plate), which makes manufacturing more compact and reduces material last. This makes it possible to reduce weight and downsize.

種々の効果を奏するものである。As detailed above, in the swash plate compressor of the present invention, the Vψy double cover is covered by the rounded cylindrical rear housing, so the V line portion with the outside air is reduced and gas leakage is prevented. In addition, since the bottom of the rear housing has only a discharge chamber and is held down by a stepped part like a valve plate and a bulging part, it is effective when a suction chamber is formed in addition to the discharge chamber. The gas vent is V- with respect to the barrier and yy end face.
Furthermore, since the rear housing can be formed using a thin steel plate, it has various effects such as reducing the amount of material used and reducing the weight and size. be.
