| (54) | RECIPROCATING COMPRESSOR SUCTION VALVE STRUCTURE AND RECIPROCATING COMPRESSOR |
| (57) A reed valve used as a suction valve (21) of a reciprocating compressor (1) has a
tongue-form arm portion (23), an outer side form of the arm portion (23) is formed
of a slit portion (24) provided in a suction valve sheet (22), and an inner side form
of the arm portion (23) is formed of an aperture portion (25) provided in the suction
valve sheet (23). An outer side reference line (L2) that coincides with the outer
side form and an inner side reference line (L3) that coincides with the inner side
form are caused to incline so as to intersect with a central line (L4) of the arm
portion (23) that passes through both a central point (P2) of a cylinder bore (12)
and a central point (P3) of a suction port (20), whereby a width of a base side (24c)
of the arm portion (23) is greater than a width of a leading end side (24a). Furthermore,
an angle (Rl) of inclination of the outer side reference line (L2) from the central
line (L4) is a predetermined value or more greater than an angle (R2) of inclination
of the inner side reference line (L3) from the central line (L4).
