摘要： An electrohydraulic system having an adjustment device for a valve includes a drive apparatus, a control apparatus, and a preloading apparatus. In the event of a fault, the energy stored in the preloading apparatus can be transferred to the control apparatus such that a rotational motion of the control apparatus begins, which leads to the adjustment of the valve. The preloading apparatus comprises at least one elastic element, which is arranged adjacent to a control shaft of the control apparatus, is stationarily connected to the control shaft, and applies a torque to the control shaft.

摘要： A safety device for detachably locking the output member of a linear drive has a coupling rod that can be coupled with the output element of the linear drive. A blocking unit is linearly movably penetrated by the coupling rod that is relatively movable with respect to the housing between a locking position blocking the stroke of the coupling rod and a release position enabling the linear movement of the coupling rod. A spring device prestresses the blocking unit in the blocking position and a locking device locks the blocking unit in the release position. The locking device has locking rolling elements in the housing and a support sleeve that is linearly movably penetrated by the coupling rod. When energized, an electromagnet device holds the support sleeve in the support position against the recoil force of at least one trigger spring of a trigger spring device.

摘要： A valve includes a valve housing body extending along a central longitudinal axis (X) between a first end and a second end. The valve housing comprises a first chamber at said first end comprising a gas inlet for receiving a gas and a second chamber at said second end having a plug provided at said second end, and an inter-chamber passageway connecting said first chamber to said second chamber. The valve further comprises a gas outlet provided in said inter-chamber passageway, and a piston provided in said inter-chamber passageway. The piston is movable between a first position wherein said outlet is blocked by said piston and a second position wherein said outlet is not blocked by said piston. The plug has a ventilation passageway extending therethrough. The valve has bypass channel configured to fluidly connect the first chamber to said second chamber and is not aligned with the ventilation passage.

摘要： A multi-port valve assembly, which includes a housing, a rotor disposed in the housing such that the rotor is operable for being placed in a plurality of positions, and a first channel integrally formed as part of the rotor. The multi-port valve assembly includes various ports which are all integrally formed as part of the housing. The rotor is rotated such that the multi-port valve assembly is placed in one of a plurality of configurations having two or more flow paths, providing fluid communication between the various ports. The rotor may include a first side channel, a second side channel fluidically isolated from the first side channel, and where the first side channel and the second side channel are fluidically isolated from the first channel. The rotor may also a first channel and a second channel, and the second channel is fluidically isolated from the first channel.

摘要： An adjustment device for a water delivery unit includes a valve body extending along a longitudinal axis with a water inlet and outlet, a shutter arrangement to control water flow from the inlet to the outlet, a first actuating member movable along the longitudinal axis to arrange shutter arrangement into opening and closing positions to respectively enable/disable the passage of water and a second actuating member rotatable about the longitudinal axis to vary the opening position of the shutter arrangement to adjust a flow rate of the water exiting the valve body. The device has a manual control member coupling with the first and second actuating members and configured to receive a manual action by a user for opening, closing and adjusting the flow rate of the water. The second actuating member cooperates with the shutter arrangement through a cam arrangement for varying the opening position of the shutter arrangement.

摘要： A valve for use with breathing assistance apparatus comprises first, second and third ports (21, 22, 23) for respective connection to a patient breathing tube, a first ventilation apparatus and a second ventilation application. The valve includes a bistable valve mechanism having a first stable configuration in which the first port is in fluid communication with the second port and not the third port; and a second stable configuration in which the first port is in fluid communication with the third port and not the second port. The valve has an actuator configured to transition the bistable valve mechanism between the two stable configurations and preventing the valve mechanism from maintaining a stable intermediate position between the first and second stable configurations. In this way a patient may be switched from one ventilation apparatus to another ventilation apparatus without sudden loss of pressure in the disconnecting circuit causing potentially infected aerosols to be released, and the without sudden loss of positive end expiratory pressure to the patients lungs.

摘要： A steam valve has a tubular stop valve configured to move toward an upper end side and a lower end side along an axial direction when the stop valve is opened and closed respectively; and a valve main body configured to accommodate the stop valve. The stop valve has a ring-shaped protrusion portion protruded outwardly in a radial direction. The valve main body has an accommodation space for accommodating the protrusion portion which is divided by the protrusion portion into a first pressure space and a second pressure space. First and second feed/discharge portions configured for adjusting a pressure in the first pressure space and the second pressure space respectively are further provided. The protrusion portion is moved upwardly and downwardly by adjusting the pressure in the first pressure space and the second pressure space.

摘要： A multi-directional touch valve has a valve unit and a press unit. The valve unit has a housing, a main flow channel, and a switching unit. The housing has a shoulder portion being adjacent to an outlet end of the housing. The switching unit is mounted in the housing and selectively blocks the main flow channel. The press unit is connected with the valve unit and has a passing portion, a hanging portion, and an abutting portion. The hanging portion is movably held on the shoulder portion and has an inner edge spaced from an outer surface of the housing and a space formed in a side of the at least one hanging portion facing the passing portion. The press unit can be pressed from any of axial direction, transversal directions, and oblique directions to switch the switching unit.
