Title:
EJECTOR AND EJECTOR-TYPE REFRIGERATION CYCLE
Document Type and Number:
WIPO Patent Application WO/2016/143291
Kind Code:
A1
Abstract:
An ejector equipped with nozzles (21, 32) for spraying a coolant, bodies (22, 30) having coolant aspiration ports (22a, 31b) and a booster unit (20g), channel-forming members (23, 35) inserted into the nozzles, and drive devices (23a, 37) for displacing the channel-forming members. The nozzle channels (20a, 25a) formed between the nozzles and the channel-forming members are provided with minimum channel cross-section sections (20b, 25b), tapered sections (20c, 25c), and fan-shaped sections (20d, 25d). The locations of the channel-forming members where the minimum channel cross-section changes are defined as tip sections (23b, 35a), while the displacement amount when displacing the channel-forming members toward the side that increases the minimum channel cross-section is defined as the increase-side displacement amount (δ). The tip sections are formed in a shape exhibiting an increase in the minimum channel cross-section as the increase-side displacement amount increases.
