Abstract: A valve and valve cartridge assembly can provide an opening and closing operation with a low torque. The valve and valve cartridge assembly can be switched between a first transmission relationship and a second transmission relationship, and the first and second transmission relationships are formed between the top of the valve cartridge and a transmission device. The first transmission relationship is established so that the valve cartridge is driven to rotate axially. The second transmission relationship is established so that the transmission member drives the valve cartridge to carry out a squeeze sealing movement.

Abstract: A valve cartridge assembly comprises a valve cartridge (9) and a transmission device. A recess (90) is formed on the top of the valve cartridge. The transmission device is provided in the recess (90) of the valve cartridge. A first transmission relationship and a second transmission relationship are formed between the transmission device and the recess (90) of the valve cartridge. The first transmission relationship is established so that the transmission device drives the valve cartridge (9) to rotate axially. When the movement in the first transmission relationship is ended, the relationship between the transmission device and the valve cartridge (9) switches from the first transmission relationship to the second transmission relationship. The second transmission relationship is established so that the transmission device drives the valve cartridge (9) to carry out a squeeze movement, and the squeeze movement enables the valve cartridge to have a moving component at least in an axial direction.
