Title:
TWO-POSITION EIGHT-WAY VALVE AND ELECTRIC VEHICLE AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/095758
Kind Code:
A1
Abstract:
A two-position eight-way valve, comprising a valve body (1), a sliding column (2), and a control mechanism (3). The valve body (1) is provided with an accommodating space (19) having an opening (191). The control mechanism (3) is connected to the opening (191). Provided on a sidewall of the accommodating space (19) are a first through hole (11), a second through hole (12), a third through hole (13), a fourth through hole (14), a fifth through hole (15), a sixth through hole (16), a seventh through hole (17), and an eighth through hole (18) allowing the accommodating space (19) to be in communication with the external environment. The sliding column (2) is provided within the accommodating space (19) and is connected to the control mechanism (3). The control mechanism (3) drives the sliding column (2) to shift and move between a first position away from the opening (191) and a second position in proximity to the opening (191), thus controlling the opening and closing of the a first through hole (11), the second through hole (12), the third through hole (13), the fourth through hole (14), the fifth through hole (15), the sixth through hole (16), the seventh through hole (17), and the eighth through hole (18). An electric vehicle air conditioning system having the two-position eight-way valve. The structure implements the integration of the functions of multiple solenoid valves, is not only inexpensive and easy to control, but is also convenient to mount, and increases production efficiency.
