An adjustment device designed to adjust a flow rate of a fluid flowing in a duct, including a body in which an adjustment valve is mounted, movable in rotation about an adjustment axis, the body having an area upstream of the adjustment axis and a downstream area opposite to the upstream area with respect to the adjustment axis, where the adjustment axis is equipped with connecting means which cooperate with at least one first control member positioned in the downstream area and a second control member positioned in the upstream area.

A valve device increases or decreases a flow rate of EGR gas. The valve device includes a housing, a bypass valve body, an EGR valve body. The housing includes: a first upstream passage into which the EGR gas cooled by an EGR cooler flows; a second upstream passage into which the EGR gas that bypasses the EGR cooler flows; a junction connected to each of a gas-flow downstream of the first upstream passage and a gas-flow downstream of the second upstream passage; and a downstream passage connected to the first upstream passage and the second upstream passage via the junction. The bypass valve body is provided in the second upstream passage. The EGR valve body is provided in the downstream passage.

A ball valve includes a valve body. The valve body is driven to rotate through a drive train that includes a planetary gear set. A gear of the planetary gear set is integrally formed with the valve body. In an embodiment, a ring gear of the planetary gear set is integrally formed with the valve body.

A performance indication device for a filter is provided. The performance indication device includes a water metering device to convert the energy of water flowing through the filter into mechanical rotation of a drive gear. A gear reduction assembly operably couples the drive gear to a valve gear and reduces the rotational speed of the valve gear relative to the drive gear. A flow controlling device is operably coupled to the valve gear and is configured to reduce or terminate the flow of water through the performance indication device and the filter when a target flow capacity is reached. The performance indication device thus provides an accurate indication to the user as to when the filter capacity has been expended without the need for a complex control system or communication link or any modification of the appliance in which the filter is installed.

A valve includes a housing having a housing cavity and at least two housing openings. A valve body is rotatably provided in the housing cavity and includes a valve body top portion, a valve body bottom portion and a valve body sidewall. The valve body sidewall has an upper valve body sidewall and a lower valve body sidewall which are connected to each other. An outer surface of the upper valve body sidewall is a partial cylindrical surface, and an outer surface of the lower valve body sidewall is shaped to have a gradually decreasing diameter in a direction from top to bottom. A seal is provided on the valve body sidewall and the seal is configured to match with the housing to enable the valve body sidewall to close at least one of the housing openings.

A coolant control valve, including: a housing with a first port and a second port; a primary rotary valve disposed within the housing and including a primary body; and a secondary rotary valve disposed within the housing and including a secondary body. The primary rotary valve and the secondary rotary valve are rotatable around the axis of rotation by at least one actuator to a first configuration. In a first configuration of the primary rotary valve and the secondary rotary valve around the axis of rotation: a first straight line, orthogonal to the axis of rotation, passes through the primary body and the first port; and a second straight line, orthogonal to the axis of rotation and co-planar with the first straight line, passes through the secondary body and the second port.

A throttle valve device includes a shaft in a cylindrical passage, a slit passing through the shaft from one lateral side to another lateral side of the shaft, a pair of bearings on both sides of the cylindrical passage and rotatably supporting one end part and another end part of the shaft, and a circular-plate valve inserted into the slit of the shaft and rotatable to open and close the cylindrical passage. A length of the slit on the one lateral side of the shaft is, in an axial direction of the shaft, longer than a length of the slit on the other lateral side of the shaft. A round end hole is formed at an end of the slit in the one end part of the shaft on the one lateral side of the shaft.

A power-assisted pipeline valve, including a valve body and a pressure relief assembly. A top of the valve body is provided with a first chute. A sliding sleeve is disposed in the valve body and has two sides respectively connected to an inner wall of the valve body through a first spring. A ball valve assembly is disposed in the sliding sleeve and connected to a valve stem. The valve stem passes through the sliding sleeve and is sleeved with a sliding shell, and the sliding shell is disposed in the first chute and provided with a rack and an electric power-assisted mechanism which is connected to the valve stem. The top of the valve body is penetrated by a first rotating shaft which is orderly sleeved with a fifth gear, a rotary table and a third spring from top to bottom. The fifth gear is meshed with the rack. The rotary table is connected to the fifth gear through a centrifugal locking mechanism. The third spring is connected to the rotary table and the valve body respectively. The pressure relief assembly is disposed on the valve body and connected to the rotary table. The present disclosure effectively solves the problems in the prior art that it is laborious for a person with a small strength to operate a manual valve, and a water hammer prevention effect is poor, which seriously affects the service life of the manual valve.

A fluid control valve includes a valve assembly having a ring gear, an array of first rotary valve bodies, an array of second rotary valve bodies, and a sealing plate. Each of the first rotary valve bodies includes at least one first flow path formed therethrough and each of the second rotary valve bodies includes at least one second flow path formed therethrough. The sealing plate includes a plurality of flow openings formed axially therethrough with each of the flow openings configured to provide fluid communication between one of the first flow paths of the array of first rotary valve bodies and one of the second flow paths of the array of second rotary valve bodies. Rotation of the ring gear causes selective rotation of the first and second rotary valve bodies to alter the flow configuration present between the arrays of the first and second rotary valve bodies.

This disclosure relates to a valve comprising a housing, an actuating shaft and a plurality of groups of valve body elements. The plurality of groups of valve body elements are disposed in the housing and capable of rotating in the housing. The actuating shaft is configured to selectively actuate at least one group of valve body elements in the plurality of groups of valve body elements to rotate. The valve is provided with a plurality of fluid passages therein, and the actuated at least one group of valve body elements can connect or disconnect at least one of the plurality of fluid passages. The valve provided by the present disclosure can control and switch more fluid passages when an output power of an actuating device is limited.
