Abstract
The present invention relates to a suction pulsation reducing device of a swash plate type compressor, and more particularly, to a suction pulsation reduction apparatus provided on a suction channel formed in a rear head of a swash plate type compressor, in which a moving range of a core portion is limited and all parts to be mounted on a suction channel are integrally formed in a case.
Claims10
A suction pulsation reduction apparatus provided on a suction channel formed in a rear head of a swash plate type compressor comprising:
- a case including an inlet located at a suction port side and having one side of the case opened in a longitudinal direction, an outlet formed by making a predetermined region on an outer circumferential surface hollow, and a latching portion protruding outwardly from the outer circumferential surface of an end part of the case;
- a core portion moving in the longitudinal direction in the case according to a suction pressure of a coolant introduced from the inlet to control an opening/closing area of the inlet;
- an elastic spring inserted into the case and seated on an other side surface of the case to elastically support the core portion,
- a core hook portion protruding inwardly in a predetermined region on an inner circumferential surface of the case;
- and
- a hook moving groove extending in the longitudinal direction on an outer circumferential surface of the core portion at a position corresponding to the core hook portion and depressed inwardly,
- wherein the hook moving groove extends from a point spaced by a predetermined distance from an other end of the core portion in the longitudinal direction, and
- wherein the core hook portion protrudes at a point spaced by a predetermined distance from the other end of the core portion in the longitudinal direction of the case, and the distance spaced from the other end of the core portion is equal to or shorter than a length of the hook moving groove.

- a core guide protruding inwardly in a predetermined region on the inner circumferential surface of the case and extending from one side to the other side in the longitudinal direction, and
- a guide moving groove extending in the longitudinal direction on an outer circumferential surface of the core portion at a position corresponding to the core guide and depressed inwardly;
- wherein the hook moving groove extends from a point spaced by a predetermined distance from an other end of the core portion in the longitudinal direction.
