A hydrostatic valve arrangement for flushing pressure medium from a working line of a hydraulic circuit includes a flushing valve with a first flushing connection for connecting to a first working line and an output connection for connecting to a pressure medium sink. The arrangement also includes a pressure valve arranged in a pressure medium flow path of the arrangement from the output connection in the direction of the pressure medium sink. The pressure valve has a valve body on which a force equilibrium is formed. The force equilibrium includes a pressure equivalent that acts on the valve body in a direction that blocks the pressure medium flow path and an opening pressure that acts in a direction that opens the pressure medium flow path and is dependent on the pressure at the output connection. The arrangement further includes an adjusting device for shifting the force equilibrium.

Fluid apparatus and related methods are disclosed. An example fluid apparatus includes a body defining a fluid flow path between an inlet and an outlet. A flow control member is positioned in the fluid flow path. The flow control member has a base pivotally coupled to an inner wall of the body defining the fluid flow path. The flow control member has an annular tip that is to flex between an open position to allow fluid flow through the fluid flow path and a closed position to prevent fluid flow through the fluid flow path.

Vacuum cooling assemblies for cooling a beverage are disclosed herein. In an embodiment, the vacuum cooling assembly may include a container compartment, a container disposed within the container compartment, and at least one beverage supply line in communication with the container compartment. The at least one beverage supply line may be configured to supply the beverage to the container within the container compartment. The vacuum cooling assembly also may include at least one vapor trap in communication with the container compartment. Moreover, the vacuum cooling assembly may include a vacuum pump in communication with the at least one vapor trap. The vacuum pump may be configured to create a vacuum in the at least one vapor trap and the container compartment, causing at least a portion of the beverage to evaporate, thereby vacuum cooling the beverage within the container.

A microfluidic control apparatus, such as a relief valve, includes a pressure containing housing to contain a fluid within an interior of the pressure containing housing, and a nanotube in fluid communication between the interior of the pressure containing housing and an exterior of the pressure containing housing. The nanotube is used to contain water therein such that, below a predetermined temperature, the water within the nanotube prevents pressure relief through the nanotube from the interior to the exterior of the pressure containing housing, and above the predetermined temperature, the water within the nanotube enables pressure relief through the nanotube from the interior to the exterior of the pressure containing housing.

A pressure relief assembly for providing thermal expansion protection to plumbing lines in a water distribution system for a home or business having a clothes washing machine wherein the water supply valve or valves and the drain connection for the washing machine are provided in a washing machine box mounted in a wall cavity, the assembly comprising a water pressure relief valve connected within the washing machine box to a washer supply line before the washer supply valve with the drain line from the pressure relief valve extending to the drain opening in the washing machine box. Optionally, the washer water supply valve is also in fluid communication with a water hammer arrestor within the washing machine box.

The T&P relief valve includes a valve spring which is sealed within a protective chamber configured to contain a first protective fluid. The valve spring is protected, by the protective chamber and first protective fluid, from corrosion, calcification and/or mineral deposits which would affect the valve assembly. A thermal element assembly is carried by an internal tongue of the valve casing. A plunger casing is configured to contain a second protective fluid to protect the upper end and captive plunger from corrosion, calcification and/or mineral deposits which could affect the thermal element. The protective chamber includes a sealing flange at a top thereof. An end cap assembly includes an end cap secured to the flange of the valve casing with the sealing flange of the protective chamber therebetween to define a casing seal for the protective chamber and the open top of the valve casing.

A heat dissipation assembly includes a case and a partition structure. The case has a chamber. The partition structure includes a partition wall vertically disposed in the chamber to separate a first flow path and a second flow path in the chamber, and the partition wall has a breach and a valve structure disposed at the breach, wherein the valve structure covers the breach when the valve structure is not pushed open. When a fluid pressure existed in a section of one of the first flow path and the second flow path which is adjacent to the valve structure is greater than a fluid pressure existed in a section of the other one of the first flow path and the second flow path which is adjacent to the valve structure, the valve structure is pushed away to expose at least a part of the breach.

A pressure cap structure for a cooling system having variable opening pressure, which is applied to a cooling system for circulating cooling water to radiate heat generated by an engine of a vehicle, and maintains the inside pressure of the cooling system in a predetermined range, the pressure cap may include a positive pressure spring mounted in a valve body, and operated to connect the cooling system to the outside when the pressure of the cooling system rises, and a shape memory member restored to the initial shape when reaching a predetermined temperature, and mounted between the positive pressure spring and a spring guard supporting the positive pressure spring.

A fuel system is provided that includes a fuel tank, a heat detector, and a control circuit. The digital heat detector is disposed in proximity to the fuel tank. The control circuit is coupled with the digital heat detector and is configured to detect that a thermal event has occurred. The fuel system is configured to implement an emergency countermeasure in response to the detection of the thermal event.

Described herein is a safety valve for a hydraulic circuit comprising a pump designed to supply a hydraulic fluid at a first pressure value to a pressure line, comprising: a chamber, which can be fluidically connected to the pressure line and is filled with the hydraulic fluid at a pressure value and a temperature value; and a casing with an opening, which can be connected to a reservoir of the hydraulic circuit; a shutter, which delimits the first chamber and can be displaced between a first position, in which it occludes the first opening, and a second position, in which it leaves the opening at least in part free; the valve comprises a thermally expandable element, which can be displaced, as a result of the temperature of the hydraulic fluid, between a first configuration that it assumes when the temperature of the hydraulic fluid is below the threshold value and a second configuration that it assumes when the temperature of the hydraulic fluid is above the temperature threshold value and in which it holds or displaces the first shutter in or towards the second position so as to reduce the pressure in the first chamber.
