Abstract

A reciprocating motor compressor for refrigerating apparatus comprises a sealed casing and a motor-compressor unit. The compressor of the unit comprises a piston, a cylinder (22) in which the piston is movable to and fro and a valved cylinder head (24). The cylinder (22), at least in the vicinity of the cylinder head (24), has at least one cooling cavity (40, 40a, 40b) in its wall with an inlet opening (42) and an outlet opening (44) to which respective cooling tubes lead which extend out from the motor compressor casing to be connected to an external coolant fluid circulation circuit for the cylinder (22).
