    摘要: A base plate 41 of a movable scroll member 4 has, at its outer periphery, a section 44 with no scroll wall, while a scroll wall 22 of a stationary scroll member 2 has a section 24 for connecting to an outer cylindrical shell 22. These sections 44 and 24 make a relative lateral slide movement during an orbital movement of the movable scroll member 4 with respect to the stationary scroll member 2. These sections 44 and 24 have axially faced inner and outer edges 44-1 and 24-1, over which the relative lateral movement occurs. These inner and outer edges 44-1 and 24-1 are bevelled, the bevelling being such that any skewed movement of the movable scroll member with respect to the stationary scroll member does not cause locally increased contact pressure, thereby preventing galling as well as seizing.

    摘要: A scroll member has a scroll wall having an axial end having a transverse surface on which a groove 20 is cut along the spiral direction of the scroll wall, to which groove a seal member contacting a facing scroll member is received. The scroll wall has a radially inner portion having a width larger than the width of the remaining part of the scroll wall. At the radially inner portion, the groove is also widened. When molding the scroll member, a recess deeper than the depth of the groove to be machined is created. The groove is obtained by machining the scroll member as molded by a milling tool. The widened portion of the groove is formed by moving a milling tool along a closed trajectory, so that the recess is left un-machined.

    摘要: A channel groove pattern 38 allowing the passage of a permeated liquid having passed through a filtration membrane 37 is provided on one filtration plate surface of a filtration plate 36, and a permeated liquid outlet nozzle 39 is provided on the filtration plate 36. The channel groove pattern 38 includes multiple channel grooves 38a, and a header groove 44 for averaging suction pressures is formed on the filtration plate 36. An area where the channel groove pattern 38 is formed is divided into upper and lower water collection areas 46 and 47 by the header groove 44. The permeated liquid outlet nozzle 39 and the header groove 44 communicate with each other through the channel grooves 38a of the water collection area 46, and the channel cross-sectional area of the header groove 44 is larger than that of the channel groove 38a.
