 the swash plate chamber becomes excessively high due to a bleeding of a blow-by refrigerant gas from cylinder bores into the swash plate chamber. In this compressor, a small amount of lubricant oil separated from the refrigerant gas, due to an impingement of the oil-containing refrigerant gas upon the internal wall of the suction passageway when entering the compressor from an external refrigerating circuit, is allowed to enter the swash plate chamber through the above-mentioned small hole. Nevertheless, such a small hole is unable to positively separate the lubricant oil from the lubricant oil-containing refrigerant gas, to thereby draw the lubricant oil into the swash plate chamber. This is because the small hole has different action from that of a baffle plate, and cannot function to deaden the flow inertia of the lubricant oil-containing refrigerant gas when it enters the compressor from the outside. Namely, the small hole of the typical conventional swash plate type compressor cannot function to separate the oil component from the refrigerant gas. Polyunsaturated fatty acids (PUFAs) are considered to be useful for nutritional applications, pharmaceutical applications, industrial applications, and other purposes. However, the current supply of PUFAs from natural sources and from chemical synthesis is not sufficient for commercial needs. PUFAs derived from microorganism such as microalgae can be produced in large scale while avoiding the contamination issues associated with fish oils.
Polyketide synthase (PKS) systems are generally known in the art as enzyme complexes related to fatty acid synthase (FAS) systems, but which are often highly modified to produce specialized products that typically show little resemblance to fatty acids. It has now been shown, however, that polyketide synthase-like systems exist in marine bacteria and certain microalgae that are capable of synthesizing polyunsaturated fatty acids (PUFAs) from acetyl-CoA and malonyl-CoA. These systems are referred to herein as PUFA synthases, PUFA synthase systems, PUFA PKS systems, or PKS-like systems for the production of PUFAs, all of which are used interchangeably herein.

Nevertheless, such a small hole is ineffective to positively separate the lubricant oil from the lubricant petroleum - containing refrigerant gasoline, to thereby draw the lubricant oil into the swash plate chamber. This is because the small fix has different action from that of a baffle plate, and cannot function to deaden the flow inertia of the lubricant oil - containing refrigerant gas when it enters the compressor from the outside.
