Abstract: A device for controlling the flow of a fluid through a conduit from an upstream side of the device to a downstream side of the device. The device includes an upstream valve casing defining an inlet, a downstream valve casing defining an outlet aperture, and a valve core secured between the upstream valve casing and the downstream valve casing. The upstream valve casing, the downstream valve casing and the valve core are formed as discrete parts. The valve core includes a housing defining a control volume. The valve member is mounted on the housing and positioned on the upstream side of the outlet aperture, the valve member being arranged to move reciprocally to selectively open and close the outlet aperture, thereby controlling flow of the fluid through the outlet aperture.

Abstract: Disclosed are a valve needle and an electronic expansion valve having the valve needle. The valve needle is provided with a connecting end and a blocking end that are arranged opposite to each other; the blocking end includes a blocking segment, a first opening segment, and a second opening segment that are sequentially connected in an axial direction; the blocking segment cooperates with a valve port to block the valve port; a cross sectional area of the blocking segment close to the connecting end is greater than a cross sectional area of the blocking segment distant from the connecting end; a cross sectional area of the second opening segment close to the connecting end is greater than a cross sectional area of the second opening segment distant from the connecting end; and a cross sectional area of the first opening segment remains unchanged.

Abstract: A device for controlling the flow of a fluid through a conduit from an upstream side of the device to a downstream side of the device. The device includes a valve housing having defined therein a valve aperture, a valve member movably mounted relative to the valve aperture. The valve member is arranged to be displaced reciprocally in a direction to selectively open and close the valve aperture. The device also includes a magnet mounted on or relative to the valve member, with the magnet being displaced by displacement of the valve member. A plurality of magnetic field sensors are mounted on the valve housing.

Abstract: The disclosure provides an anti-lock brake device including an oil pressure tank, a valve, and a movable component. The oil pressure tank has an accommodation space, an oil inlet channel, and an oil outlet channel connected to the accommodation space. The valve is slidably located in the oil inlet channel and for sealing or opening an oil inlet of the oil inlet channel. The movable component is located in the accommodation space and has a connecting channel corresponding to the oil inlet and an oil outlet of the oil outlet channel. When the movable component is slid to a depressurized position, the movable component is moved away from the valve for sealing the oil inlet, a first volume is produced between the connecting channel and the oil inlet, and a second volume, smaller than the first volume, is removed from between the connecting channel and the oil outlet.

Abstract: A fluid flow-control valve has a housing having an inlet port and an outlet port and forming a flow passage extending therebetween and a valve spindle having a valve cone that fits with a valve seat formed in the flow passage for controlling flow between the inlet port and the outlet port. An elastically movable film sensor near or on the spindle has one face exposed to a static pressure of a flow of fluid in the passage and an opposite face to a total pressure of the fluid applied to the end face of the valve cone for determining a differential pressure therebetween and generating an output signal transferrable to a measured value device. Thence the signal is communicated with an evaluation device, a regulation and control device, a device for influencing the volume flow, and/or an actuating device.

Abstract: An inline valve includes a sliding piston having a radially outer stop portion with a forward end. A radially inner sliding portion is connected to the radially outer stop portion by an arm. A housing includes an outer housing body surrounding the piston. The housing has a stop surface selectively in contact with the forward end of the radially outer stop portion of the piston to block flow for a housing inlet to a housing outlet. The radially inner sliding portion slides on a support tube. At least a portion of the radially inner sliding portion is formed of a first material having better wear resistance than a second material forming the outer stop portion of the piston. The second material has a greater resistance to high temperature and pressure than the first material. A vent valve for a compressor is also disclosed.

Abstract: The invention relates to a gas valve (1), comprising:
a valve body (2) which is hollow-cylindrical at least in parts and which forms a sealing seat (3) over which a gas flow path (4) is conducted,
a reciprocating valve closure element (5) which is accommodated at least partly in the valve body (2) and which has a plate-like end portion (6) arranged outside the valve body, (2) which end portion interacts with the sealing seat (3),
a sleeve (7) which at least partially surrounds the valve body (2) and the valve closure element (5) and which, together with the plate-like end portion (6) of the valve closure element (5), delimits an annular gap (8) which forms a throttle point in the gas flow path (4) downstream of the sealing seat (3).-

Abstract: A coaxial liquid pressure regulator includes a housing having an inlet portion and an outlet portion, a substantially tubular valve member slidingly accommodated inside the housing and having a longitudinal axial passage and an upstream end with an inlet edge for the liquid, a valve body fixed inside the inlet portion and defining a seat that interacts with the inlet edge of the valve member and forms therewith a port having a variable width. The inlet portion includes an inlet fitting and a collection chamber directly downstream from the inlet fitting and the valve body includes a cantilever element transversely extending from the inner wall of the collection chamber. First and second deflection elements are arranged between the inlet fitting and the inlet edge, which facilitate flow conveyance toward the port and the longitudinal passage of the valve member.
