The disclosure relates to a motorised air circulation valve including a gear motor, a valve body, and a rotary shaft provided with a shutter. The rotary shaft is rotated by the gear motor, where gear motor includes a set of reduction gears, a brushless electric motor formed by a rotor having N pairs of magnetised poles connected to a pinion of the set of reduction gears, and the pinion drives an output wheel rigidly connected to the rotary shaft. The electric motor includes a stator part having at least two coils, the stator part having two angular sectors, alpha1 and alpha2, of respective radii R1 and R2, with R1 being greater than R2, and the center of the radii and the angular sectors being defined relative to the center of rotation of the rotor. The angular sector alpha1 is defined by the angular deviation between the axes of the first and last coils considered in a circumferential direction of the motor, the angular sector alpha1 is less than 180° and includes the coils, the sector alpha2 is devoid of a fully fitted coil, an end of the gear motor defines a side of the gear motor, and the angular sector alpha2 of the stator part is positioned facing the side.

A valve comprising a valve body including a first end and a second end spaced apart along a longitudinal axis, a central portion disposed between the first end and the second end, wherein the first end and the second end define a first flow passageway and a second flow passageway, respectively, and wherein the central portion defines an interior chamber, a stem rotatably supported by the valve body about a rotation axis, wherein the stem includes a polygonal end, and a disc disposed within the interior chamber and including a polygonal aperture to receive the polygonal end of the stem.

An installment method of a fluid control body and a fluid control device including a fluid control body with which processes of designing, manufacturing, and managing the fluid control body are simplified to suppress cost of manufacturing, etc, includes a cut-off step of cutting off part of a fluid pipe inside a casing, and an installment step of installing the fluid control body including an on-off valve formed by a valve seat body and a valve element, and a partition body formed by a wall portion, a lid portion, and a seal component, inside the casing in a sealed manner in a state where an operation shaft of the on-off valve is placed in a direction different from the vertical direction.

A new and innovative high-pressure priming valve is provided for use in high-pressure fluid systems that require a high level of fluid purity. The priming valve includes at least three ports, some of which are angled. The priming valve also includes a needle that variably blocks and unblocks a pathway to one of the ports between normal operation and a priming operation, respectively. The priming valve includes a sealing insert positioned below a stack of washers that maintain the needle's alignment in response to high fluid pressures exerted on the needle. The sealing insert helps prevent fluid from contacting the stack of washers, which helps prevent biological growth within the valve. The angled ports help facilitate priming valve drainage to further help prevent biological growth. By helping prevent biological growth, the sealing insert helps prevent fluid contamination and enables the priming valve to be utilized for high-purity fluid applications.

A system for gas extraction is provided with a flap valve coupled to a bore with a pivot axis offset from an axis of the bore. The valve includes a higher mass on a shorter side of the pivot axis. A valve surface on the shorter side is inclined above a horizontal plane when the valve closes. The valve opens during liquid and gas flow to extract gas from the flow. As liquid flows over the valve, the valve is forced to close. The center of gravity of the valve relative to the offset pivot point ensures that the valve remains closed during liquid flow. As gas flows over the valve, closing forces are reduced and under internal vacuum, the mass distribution about the offset pivot axis allows the flap of the valve to tilt; opening the valve and allowing gas to enter the bore.

A temperature-controlling water valve is provided. An adjusting assembly is assembled within the water valve and includes an adjusting member, a first elastic member, a blocking member and an abutting member. The first elastic member biases the abutting member, and the blocking member is fixed to the adjusting member to block the abutting member from detaching from a receiving hole of the adjusting member. A temperature-controlling assembly includes a valve member and a second elastic member biasing the valve member. Thermal expansion or contraction of a rod member of the valve member drives the valve member to move so that an overlapping area of the valve member and a first passageway of the water valve and an overlapping area of the valve member and a second passageway of the water valve change.

The invention relates to a valve device (100) for a gaseous medium, in particular hydrogen, comprising a valve housing (6) which comprises a closing element (14) that is arranged therein and can be moved in the longitudinal axis (18). The closing element (14) interacts with a seal seat (16) in order to release and close a through-opening (22). The valve housing (6) is equipped with at least one spring element (8) which is supported against the closing element (14) and the valve housing (6). Furthermore, the at least one spring element (8) is made of a bimetal.

The invention discloses a reticle storage device including a top lid, a bottom lid and a soft contact member. The top lid has a ceiling and a cover surrounding the ceiling. The bottom lid has a carrier and a peripheral structure surrounding the carrier. The soft contact member is configured to laterally extend in between the cover and the peripheral structure when the top lid and the bottom lid engage with each other, and to extend from an inside to an outside of the device in order to buffer the contact among the two lids.
