摘要： The invention relates to an electronically operated control valve, for refrigeration and heating applications, comprising a main tube with two end pieces serving as inlet and outlet and an elastic part piece, which may be pressurised by an enclosing chamber to change the shape and hence flow cross-section thereof. Said enclosing chamber is filled with a filling medium, the pressure of which is dependent on the temperature thereof and which cooperates with an electronically operated pressure regulation device. The enclosing chamber (12) is formed between an extension (14) of the main tube (2) and a perforated support tube (16). The elastic part piece is made up of a hose (8), fixed and sealed at the end between the extension and the support tube. The pressure control device is embodied as a separate pressure generator (10) connected to the enclosing chamber (12) by means of a connector tube(18).

摘要： The invention relates to a coolant distributor for use between an expansion valve and an evaporator of a refrigeration installation. Said distributor comprises a central fluid/vapour inflow channel, several outflow channels, which are distributed around the inflow channel and comprise inflow openings for the fluid and the vapour, a housing, a conduction chamber for radial flow conduction and an annular chamber between the housing wall and the outflow channels, which acts as a collection chamber for the fluid and the vapour. According to the invention, the outflow channels are provided with passages in the channel wall, said passages connecting the fluid and the vapour regions of the annular chamber to the channels. The aim of the invention is to produce the distributor cost-effectively and to adapt it easily to the respective coolants and their dynamic characteristics, in addition to obtaining a satisfactory coolant distribution. To achieve this, the distributor is provided with a one-piece distributor head (4), in which the outflow channels (16) are configured and which comprises a cap (6) for controlling the inflow.
