Abstract:
A reciprocating compressor comprising:a front housing; a cylinder block, wherein a plurality of cylinder bores are formed within said cylinder block; a rear housing; a valve plate positioned between said cylinder block and said rear housing, wherein said valve plate has a suction hole formed therethrough; a plurality of pistons, each of which is slidably positioned within a corresponding cylinder bore; a drive mechanism adapted to reciprocate each of said pistons within said corresponding cylinder bore; a suction chamber formed between said rear housing and said valve plate; a suction valve reed formed on said valve plate, wherein said suction valve reed regulates the flow of a fluid through said suction hole; and a limiting recess formed within an end of said cylinder block adapted to receive said suction valve reed, wherein said limiting recess comprises at least one arced segment intersecting a center axis of said suction valve reed, such that the portion of said at least one arced segment intersecting said center axis of said suction valve reed has a corresponding tangential line at the point of intersection which forms an oblique angle relative to said center axis of said suction valve reed.
