Abstract
An oscillating-plate type compressor has five cylinder bores 6 formed in a cylinder block 1. Coolant gas compressed in the cylinder bores is discharged to a discharge chamber 12 through discharge valves 17 secured to the cylinder block 1 by means of a bolt 19. The discharge chamber 12 is separated by a baffle plate 14 into two discharge spaces 12a and 12b, the former containing a bolt head 19a and the latter communicating with the discharge port. Five holes 14a to 14e which are the same in number as that of the cylinder bores 6 are formed and arranged along an imaginary circle of a predetermined diameter around the bolt facing portion 28 of the baffle plate 14 so as to communicate both of the discharge spaces 12a and 12b with each other.
Claims12
In an oscillating-plate type compressor comprising a plurality of cylinder bores, respectively formed in a cylinder block;
- discharge valves for discharging coolant gas compressed in said cylinder bores into a discharge chamber;
- at least one bolt having a bolt head, for securing the discharge valves to the cylinder block;
- and a baffle plate for separating the discharge chamber into a discharge valve side discharge space containing said discharge valves and the bolt head, and a discharge port side discharge space coupled to a discharge port of the compressor, said baffle plate having a bolt-head facing portion which faces the bolt head of said at least one bolt,
- the improvement comprising:
- a pulsation decreasing means, including a plurality of holes formed in the baffle plate and through which both of the discharge spaces communicate with each other, for decreasing pressure pulsations during operation of the compressor;
- and
- said plurality of holes being arranged in an area of the baffle plate which is spaced from the bolt-head facing portion of the baffle plate.
