A valve trim includes a body having a plurality of parallel flow passages extending from a first end of the body to a second end of the body, opposite the first end. Each flow passage includes a throat and an expansion chamber and each throat is nested between the expansion chambers of directly adjacent flow passages.

A control method of stepwise and stepless linear adjustment of a gas oven includes step 1: obtaining the setting temperature of the gas oven; step 2.: obtaining the temperature inside the gas oven; step 3: determining the low temperature threshold, high temperature threshold and preset flame level according to the setting temperature, wherein the high temperature threshold is greater than the low temperature threshold; step 4: ensuring the temperature inside the gas oven is between the low temperature threshold and the high temperature threshold; step 5: if it exceeds, determining the change trend of the temperature inside the gas oven; step 6: when the change trend of the temperature inside the gas oven rises or falls, adjusting the flame level of the gas oven to the preset flame level.

A pluming fitting and adapter for coupling a tubing to the plumbing fitting. The adapter has first and second adapter end portion with connected fluid passageways. The second adapter end portion being insertable into the free-end portion of the tubing. A pluming fitting housing has a chamber sized to receive the first adapter end portion. When the first adapter end portion is positioned within the chamber, an outer end portion of its fluid passageway is in fluid communication with the chamber. A seal and gripper ring within the chamber seal with and releasably grip the first adapter end portion.

A method and apparatus for a manual gas valve. The manual gas valve may include at least one internal spring and a valve plug. The internal spring may be independent from an external spring and a valve stem. The internal spring may be positioned in a constant installed height. The internal spring includes a constant spring force applied to the valve plug. The one or more manual gas valves may be used in a variety of applications.

Provided are an electric valve, a thermal management assembly, and an air conditioning system. The electric valve includes a valve body, a circuit board, and a sensor. The valve body has a passage, and the sensor is connected to the circuit board in at least one of an electric connection mode and a signal connection mode. The sensor is configured to detect at least one of a pressure or a temperature of a working medium in the passage. At least one of the valve body or a housing of the sensor includes a metal portion, and a reference ground of the circuit board is electrically connected directly or indirectly to the metal portion.

An assembly is provided for a turbine engine with an axial centerline. This assembly includes a turbine engine structure and a valve assembly. The turbine engine structure includes an outer duct wall, an inner duct wall, a first flow path and a second flow path. The inner duct wall is radially inward of the outer duct wall. The first flow path is radially inward of the inner duct wall. The second flow path is radially outward of the inner duct wall and is radially inward of the outer duct wall. The valve assembly includes a valve element and a valve actuator. The valve element is configured to regulate flow of fluid between the first flow path and the second flow path. The valve actuator is configured to move the valve element. The valve actuator is positioned entirely radially outward of the outer duct wall.

A device and method for dispensing a flowable medium has a housing with an interior space and a rod mounted in the housing that is movable between a first end position and a second end position and passes through a diaphragm mounted in a sealed manner in the housing radially on the outside and in the rod radially on the inside. The diaphragm divides the interior space into a first cavity and a second cavity separated from the first cavity in a fluid tight manner. The flowable medium can flow through at least one channel that opens into the first cavity, and is dispensed through a dispensing opening. A sealing section of the rod closes the dispensing opening in the first end position and is at a distance from the dispensing opening in the second end position. A pressure medium acts on the diaphragm in the second cavity.
