A valve assembly, for controlling a fluidic connection between a brake master cylinder and a pedal simulator of a brake system of a motor vehicle, includes a first control valve and a second control valve, the second control vale being positioned between the first control valve and a pedal simulator and including first and second flow controllers to control flow volumes of hydraulic fluid that differ between first and second flow directions.

Devices and methods for mass flow verification are provided. A mass flow verifier includes a chamber configured to receive a fluid, a critical flow nozzle upstream of the chamber, a chamber valve, a downstream valve, and a bypass valve. The chamber valve is configured to selectively enable fluid flow from the critical flow nozzle to the chamber. The downstream valve is configured to selectively enable fluid flow from the chamber to a downstream location. The bypass valve is configured to selectively enable fluid flow from the critical flow nozzle to a dump location. The mass flow verifier further includes a controller configured to verify flow rate of the fluid based on a rate of rise in pressure of the fluid as detected by a pressure sensor in the chamber.

A capacity control valve includes: a valve body having first communication passages, second communication passages, third communication passages, and a main valve seat; a valve element having an intermediate communication passage, a main valve portion and an auxiliary valve portion; a pressure-sensitive element disposed in the valve body; a solenoid that drives a rod; a first biasing member that biases in a valve closing direction of the main valve portion; and a second biasing member that biases in a valve opening direction of the main valve portion, wherein the rod moves relative to the valve element to press the pressure-sensitive element. The capacity control valve can efficiently discharge a liquid refrigerant and can decrease a driving force of a compressor during a liquid refrigerant discharge operation.

A pilot-controlled coolant valve is provided that includes a pressure chamber, a pressure release chamber, a control opening, a pressure release channel, an actuator having a plunger, a control piston stroke-actuated by the plunger, a closing piston moving in the pressure chamber, and a valve seat. The pressure chamber has an in-flow and an out-flow for coolant. The control opening connects the pressure release chamber to the pressure chamber. The control piston closes the control opening during the stroke actuation by the plunger, except for a radial sealing gap between the control piston and the control opening. When the control opening is closed, the closing piston sealingly rests on the valve seat and interrupts the connection of the through-flow chamber with the in-flow. Axial end sides of the closing piston delimit a stagnation pressure chamber on one side and a through-flow chamber on the other side.

A fluid meter has a housing comprising a flow channel for fluid to be measured and at least one elongate module-receiving opening forming a passage from an outer surface of the housing to the flow channel. At least one fluid-measuring module, prefabricated separately, from the housing with a base section formed as a waveguide for surface acoustic waves, and at least one signal transformer to excite surface acoustic waves in the waveguide and/or receive surface acoustic waves from the waveguide is provided. When inserted into the module-receiving opening, the base section of the fluid-measuring module forms part of the flow channel inner wall and contacts fluid flowing through it. Surface acoustic waves emitted by the signal transformer can be coupled out of the waveguide and can propagate through fluid in the flow channel as bulk acoustic waves and/or bulk acoustic waves can be coupled into the waveguide and received by the signal transformer.

Programmable controller technology, in which data is received that identifies a particular type of irrigation system component that is to be controlled by a programmable controller. Based on receiving the data identifying the particular type of irrigation system component, configuration information is accessed for the particular type of irrigation system component. Based on the configuration information, a configuration is determined for one or more interface ports of the programmable controller. The one or more interface ports of the programmable controller are configured according to the determined configuration. A connection between the particular type of irrigation system component and the programmable controller that satisfies the determined configuration is detected. Based on detecting the connection between the particular type of irrigation system component and the programmable controller that satisfies the determined configuration, the particular type of irrigation system component is controlled through the one or more interface ports.

A multi-mode manipulated water outlet device includes a faucet body and a control box. The faucet body includes a main body, and a second induction unit, a first temperature control valve group, a first water inlet unit and a first water outlet unit that are fixedly disposed on the main body. The first water inlet unit and the first water outlet unit communicate with the first temperature control valve group. The control box includes a second temperature control valve group, and a second water inlet unit and a second water outlet unit communicating with the second temperature control valve group. The first water inlet unit communicates with the second water outlet unit. One flow path manipulation mode is provided through the first temperature control valve group, and another flow path manipulation mode is provided through the second induction unit, thereby providing two different control modes for operating the device.

An improved particulate metering system is provided. The system includes an air flow origin and a plurality of particulate accelerators. A single particulate source is in communication with the particulate accelerators. Each of a plurality of operated conveyances can be in operable communication with the single particulate source and one of the particulate accelerators. The system includes a confluence of the air flow and the particulate within the mixing area of each of the particulate accelerators. Each of a plurality of discharges can be associated with the particulate accelerators. The operated conveyances can operate at different rates. The system can include one or more gearboxes adapted to be inverted and controlled by a second drive system. The improved system and controls provide variable application rates of particulate across rows in a field.
