Abstract:
1. A rotary type compressor comprising: a movable member arranged to move in an eccentric motion; and a fixed member which cooperates with the movable member to define a compression chamber arranged such that a fluid drawn into the compression chamber is compressed when the movable member is moved in the eccentric motion; the fixed member having an end plate part with a front surface facing the compression chamber; the end plate part being provided with a receding part, which is dented from a back surface of the end plate part, formed on a back surface side thereof, a discharge passage fluidly communicating with the compression chamber and having an opening at a bottom surface of the receding part, and a discharge valve including a reed valve arranged to open and close the discharge passage; the discharge valve having a plate shaped valve disc with a front surface that abuts with the bottom surface of the receding part and a valve guard arranged to restrict an amount of deformation of the valve disc; and the valve guard having a main body part abuttable with a back surface of the valve disc and a fixation part integrally formed with the main body part and extending externally of the receding part along the back surface of the end plate part, the valve guard being mounted to the end plate part by fixation of the fixation part to the end plate part, the valve disc being entirely located in the receding part, a valve guard surface of the main body part being located nearer to a bottom surface side of the receding part than a front surface of the fixation part, and a space larger than the valve disc in thickness being located between the valve guard surface of the main body part and the bottom surface of the receding part, with the space being formed on an entire surface of the valve disc in the receding part.
