Gas flow and sound control valve for an exhaust system of an internal combustion engine comprising a housing including an inlet, a first outlet, and a second outlet, and a valve member arranged within the housing for forming a first conduit connecting the inlet to the first outlet and/or a second conduit from the inlet to the second outlet, wherein the valve member can be moved relative to the housing between a first predetermined position in which the valve member closes the second conduit and a second predetermined position in which the valve member closes the first conduit, whereby the valve member is rotatable around a valve axis aligned parallel, in particular coaxial, to a centerline of the inlet.

An easy-to-install tap structure includes a tap body, a pipe joint and a connecting pipe for communicating the tap body with the pipe joint. The connecting pipe is arranged between the tap body and the pipe joint. When the tap structure is used for a wash basin, there is no need to connect a braided hose; in the process of replacing a tap, there is no need to replace the pipe joint and the connecting pipe, so that the pipe joint and the connecting pipe can be used many times; and when the tap is dismounted, the tap body can be directly rotated, and when the tap is mounted, the connecting pipe is directly adjusted to rotate until the water outlet of the tap is arranged in the correct direction.

A vehicle thermal management system for significantly improving thermal management performance includes a first group including a battery, a second group including one or more power electronics (PE) components, a plurality of cooling lines in thermal communication with an air-cooled radiator, and a six-way valve. The six-way valve includes a housing having a plurality of inlets and a plurality of outlets, a valve member mounted to be rotatable in the housing, and an actuator driving the valve member. The housing has a plurality of passages allowing the plurality of inlets to selectively communicate with the plurality of outlets by rotation of the valve member. In addition, the plurality of passages include a plurality of inner passages formed in an interior space of the housing, and a plurality of outer passages formed in an exterior space of the housing.

In order to shift a rotation angle of a rotor to a region of a normal mode (for example, a region c) from a region of a heater cut mode (for example, a region e), the rotation angle needs to pass through a region where a flow rate of a refrigerant which is caused to flow through all branch channels becomes zero (a region d). When the refrigerant has a high temperature, there is a possibility of the refrigerant being not cooled, and boiling. Therefore, when a request to switch a normal mode and a heater cut mode is issued, permission/non-permission of switch of the mode is determined by comparison of a temperature of the refrigerant detected by the temperature sensor 26 and an upper limit temperature of the refrigerant.

A control valve includes: a port, which is shaped in a tubular form; a valve element; and a metal seal, which contacts the valve element. A gap is formed between a tubular portion of the metal seal and the port in a perpendicular direction that is perpendicular to an axial direction of a flow passage of the port. Thereby, when the valve element is displaced in the perpendicular direction, the valve element urges the metal seal to displace the metal seal in the perpendicular direction in the state where the metal seal contacts the valve element.

A rotary valve comprises a stator member with a stator face, the stator member having at least two stator channels for conducting a fluid and opening into the stator face; a rotor member with a rotor face facing and in contact with the stator face, the rotor member having a rotor channel in the rotor face, wherein the rotor member is rotatable with respect to the stator member about a rotation axis, such that in a conducting position, the rotor channel interconnects the at least two stator channels to be in fluid communication; and a rotary encoder assembly adapted for determining a rotary position of the rotor member, the rotary encoder assembly comprising an encoder member and an encoder module, which is adapted to sense a rotary position of the encoder member. The encoder member is rigidly connected to the rotor member and surrounds the rotor member.
