(57) In a suspension in which the motor-compressor ensemble is suspended through helical
springs (R) arranged between a support (S) of the compressor tub walls (C) and a point
of the compressor body (E), the border of an opening (A) for receiving the spring
end is formed with a circumferential inclined surface with two ends (2,3) mutually
close, spaced apart in the axial direction of the opening and connected by a short
run (3a), and a tenon (3b,4,6) is formed to protrude from the upper face of the support
(S), forming a stop for a bent end (5) of the helical spring (R) to limit the introduction
length of the said spring in the support (S). The borders of the opening (A) form
an inclined surface, either straight or arcuate, to rest between the spring turns.
It is thus avoided the tapping or beating of the spring turns onto the support, and
the thus arising noise.
