The upper and lower valve cores are respectively installed with the sealing member.

A fluidic valve unit having a plurality of rotary slide valves arranged in series and a servo motor for setting the rotary slide valves, wherein each of the rotary slide valves comprises a rotary slide arranged in a rotary slide housing and drivable via a driveshaft by means of the servo motor. It is provided in this case that each two successive ones of the rotary slide valves are mechanically connected to one another via a driver device for the setting by means of the servo motor, wherein the driver device comprises a driver projection arranged on a first of the two rotary slide valves.

A fluid valve device. A first rotary slide valve, a second rotary slide valve, and a servomotor are provided. Each of the rotary valves has a rotary slide arranged in a rotary slide housing and drivable via a drive shaft by the servomotor. The first rotary slide valve is rigidly coupled and the second rotary slide valve is coupled via a freewheel to the drive shaft.

A regulating valve has a housing, a first valve body, a second valve body, a third valve body, a fourth valve body, and an actuating shaft. The housing has a first cavity and a second cavity. The first valve body is disposed in the first cavity. The second valve body is disposed in the first cavity, and the first valve body and the second valve body can rotate about a first axis X. The third valve body is disposed in the second cavity. The fourth valve body is disposed in the first cavity, and the third valve body and the fourth valve body can rotate about a second axis Y. The actuating shaft is rotatably disposed in the first cavity, and the actuating shaft can selectively drive one or more of the first valve body, the second valve body, the third valve body, and the fourth valve body to rotate.

A valve, comprising: a housing, a holder, a first valve body, a bearing, and a second valve body. The housing comprises a first housing part, a second housing part, and a neck connecting the first housing part and the second housing part, a first valve body cavity is formed in the first housing part. The holder is provided in the second housing part, the holder and the second housing part together form a second valve body cavity and a pump cavity, the holder and the neck together form a bearing accommodating part for enabling the first valve body cavity to be in fluid communication with the pump cavity. At the bearing accommodating part defined by the holder and the neck, a limiter is provided, the limiter extends towards the bearing, the bearing has a receiving part, and the limiter cooperates with the receiving part to restrict movement of the bearing.

A multifunctional valve assembly includes a first portion with a first 3-way valve functionality for selectively controlling flow of a first fluid and a second portion with a second, 3-way functionality valve functionality for selectively controlling flow a second fluid. The multifunctional valve assembly further includes a common motor associated with the first and second portions and operative to drive both of the first and second portions to operate in first, second and third operational modes. A method of operating the multifunctional valve assembly including rotating a first sleeve about an axis of the first sleeve with the common motor to concurrently drive the first and second portions of the valve assembly to each operate the first, second and third operational modes.

A coolant control valve is provided that includes at least one actuator, a first rotary valve body and a second rotary valve body, each rotary valve body driveably connected to the at least one actuator. The second rotary valve body is arranged non-coaxially to the first rotary valve body.

A valve includes a valve body provided with a plug, connected to an actuation system, an upstream duct, a downstream duct, and a purge duct provided with a shutter. The plug is movable in rotation about a longitudinal axis in the valve body, so that the rotation of the plug according to a first angular sector defines a flow between the upstream duct and the downstream duct, the rotation of the plug according to a second angular sector separate from the first angular sector shuts off the connection between the upstream duct and the downstream duct, and the rotation of the plug according to a third angular sector included in the second angular sector actuates the shutter so as to allow a flow from the upstream duct to the purge duct.
