摘要： Electropneumatic solenoid valve includes an electromagnetic actuator with an energizable coil and a solenoid armature movable relative to the coil, an air chamber with three air channels, and a valve member. The three air channels include first and second air channels and a control air channel. The valve member, in a first closed position, closes the first air channel and releases the second air channel and which, in a second closed position, closes the second air channel and releases the first air channel. The valve further includes a driver movable in a first and second actuating directions and that connects the valve member to the solenoid armature, a driver-pretensioning spring arranged between the driver and the solenoid armature, to provide a pretensioning force to the driver, and a restoring spring between the driver and the electromagnetic actuator to provide a restoring force to the driver against the driving direction.

摘要： A valve includes: a valve housing provided with a primary pressure port and a secondary pressure port; a valve body configured to be driven by a solenoid; a valve seat on which the valve body is seated; and a spring that urges the valve body in a valve opening direction. The valve seat includes a first valve seat and a second valve seat disposed on a radially inner side of the first valve seat. The second valve seat is configured for moving in a direction toward the valve body due to a differential pressure between a primary pressure and a secondary pressure.

摘要： A fluid end is formed from a first body attached to a separate second body. Each body includes an external surface. When the bodies are attached, their respective external surfaces are in flush engagement. A plurality of bores are formed in the second body that are alignable with a plurality of corresponding bores formed in the first body. The fluid end may be used with seals disposed within recesses within each bore to seal against corresponding sealing surfaces. Further, retaining closures may be bolted to the fluid end bodies, such that the closures have a threadless connection to the fluid end bodies. Various combinations of such components may be utilized.

摘要： An interposed coaxial valve system designed for internal combustion engines. The system comprises a single main valve integrating two coaxial valves: an interior valve and an exterior valve. The interior valve may move independently from the exterior valve during engine operation. The system minimizes spatial occupancy for internal combustion engine valves. By interposing the interior valve within the exterior valve, the system achieves a compact and efficient design. The system may also comprise adjacent intake and exhaust ports to promote heat transfer between the two ports.

摘要： The cooling water temperature control device includes a thermo valve 2 that opens a main flow passage R1 when the temperature of a sensed region R1a in the main flow passage R1 reaches or exceeds an operating temperature set in advance, a sub-valve 3 that opens and closes a sub-flow passage R2 bypassing the thermo valve 2, and a control unit 6 that opens the sub-valve 3 when the temperature of the cooling water on an upstream side of the thermo valve 2 is a predetermined temperature. One end on the upstream side of the sub-flow passage R2 is connected to the sensed region R1a in the main flow passage R1 or to a downstream side of the sensed region R1a, and the operating temperature of the thermo valve 2 is set to be equal to or lower than the predetermined temperature.

摘要： A pipe cleaning assembly has a connection fixture having a body defining a cavity. A first aperture, opposing second aperture coaxially aligned with the first aperture, first auxiliary aperture, and opposing second auxiliary aperture coaxially aligned with the first auxiliary aperture are in fluid communication with the cavity. A first connection flange extends from and surrounding the first aperture and a second connection flange extends from and surrounding the second aperture. A rotatable bonnet inserted through the second auxiliary aperture and includes a cylindrical wall having an open first end, an end wall at a second end, and a plurality of openings through the wall. An actuator is mounted to the bonnet with an actuator shaft extending through an opening in the end wall. A valve plug is secured to the actuator shaft and positioned within the bonnet.

摘要： A headset, during play of a particular game, receives a plurality of audio channels carrying game sounds and determines whether a first of the game sounds overwhelms a second of the game sounds. In response to the determination, the headset adjusts a level of one or more of the audio channels such that perceptibility of the second game sound is improved relative to perceptibility of the first game sound prior to the adjustment, wherein for the adjustment, a level of one or more of the audio channels carrying the first game sound is decreased while a level of one or more of the audio channels carrying the second game sound is maintained or increased. The audio channels include three or more audio channels and the adjustment of the level of the audio channels is performed while the three or more audio channels are combined into two stereo channels.

摘要： An example method includes moving a first portion of a control element and a second portion of the control element coupled to the first portion from a closed position to an intermediate position. In the closed position, the first portion being seated against a first valve seat thereby preventing flow through a first orifice and the second portion being seated against a second valve seat thereby preventing flow through a second orifice. In the intermediate position, flow through the first orifice is deterred and flow through the second orifice is permitted. The method includes moving the first portion and the second portion from the intermediate position to an open position. In the open position, the first portion being spaced from the first valve seat thereby permitting flow through the first orifice and the second portion being spaced from the second valve seat thereby permitting flow through the second orifice.

摘要： A fuel vapor switching and venting valve for an internal combustion engine. The fuel vapor switching and venting valve includes an electromagnet with an armature, a first connection, a second connection, a first valve seat which is arranged between the first connection and the second connection, a spring, a flow limiting element, a second valve seat which is arranged on the flow limiting element, and a valve body coupled to the armature of the electromagnet. The valve body has a first contact surface with which the valve body can be lowered onto and lifted off of the first valve seat, and a second contact surface with which the valve body can be moved against the second valve seat. The second valve seat is axially displaceable. The spring loads the second valve seat in a direction of the valve body.
