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 water delivery control system operates to selectively deliver water from a water source to water use devices. The system includes at least one controller that wirelessly communicates messages with a portable user device. The system includes a water control valve and a motor that is operative to selectively move at least one valve element of the valve. A water meter is operative to measure water flow that corresponds to flow through the valve. The controller is operable to cause the valve to enable or prevent flow through the valve responsive at least in part to water flow data. The controller is operative to determine a water use condition responsive to a water usage pattern, and to cause at least one message to be sent to the portable user device responsive to the determined water use condition.

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 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 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.

An airbed with an air pump is provided. A main inflatable cavity is arranged inside an airbed body of the airbed, the top edge of the main inflatable cavity is surrounded by an upper inflatable cavity, and the bottom edge of the main inflatable cavity is surrounded by a lower inflatable cavity. The main inflatable cavity, the upper inflatable cavity and the lower inflatable cavity are isolated from each other. After the upper inflatable cavity and the lower inflatable cavity are completely filled, the upper and lower edges of the main inflatable cavity can be propped up, so that the whole airbed has a stable shape and excellent support. In addition, since the three set inflatable cavities are independent of each other, the other two inflatable cavities can still play a supporting role even if one of the three inflatable cavities is damaged and leaking.

An annulus pressure release system includes a gas metering valve assembly having a fluid pathway. The gas metering valve assembly includes a pressure sensor configured to be fluidly coupled to an annulus and to output a sensor signal indicative of a fluid pressure within the annulus. The gas metering valve assembly also includes an electronically actuated adjustable control valve disposed along the fluid pathway and a electronically actuated two-position valve disposed along the fluid pathway. Furthermore, the gas metering valve assembly includes a flow controller. The flow controller, in response to determining the fluid pressure exceeds a threshold pressure, is configured to output a first control signal to the electronically actuated two-position valve indicative of instructions to open the electronically actuated two-position valve, and to output a second control signal to the electronically actuated adjustable control valve indicative of instructions to adjust a flow of fluid through the fluid pathway.
