摘要： A quick-coupling between a male part (90) and a female part (92) has provided in the cylindrical end-part (134) of the male part an axially displaceable piston body (106) provided with sealing ring (108), and a sealing sleeve (134) which is provided with a sealing ring (164) and which is axially movable in the female part around a stationary piston body (138). Insertion of the male part into the female part causes the piston bodies to be brought into engagement with one another, while the cylindrical end-part is pressed inwardly by the sealing sleeve of the female part. Each of the piston bodies and respective sealing rings (108, 164) coact with a respective, axially movable valve sleeve (122, 156), in a manner such that, until the piston bodies have reached an intermediate position, a through-flow channel (132, 145) is held closed by means of a gap closed by the valve sleeve until respective sealing rings have been moved by relative displacement from one side of the gap to the other side thereof, whereafter continued displacement of the piston bodies to their respective end positions in the coupled state of the coupling causes the gaps to open for flow therethrough.

摘要： The invention relates to a coupling for hoses or the like for media under pressure. The coupling comprises a female part (1) and anipple (2) which fits into the latter and also a ball lock (3) for locking the nipple (2) in the connected position in the female part. A locking sleeve (6) is spring-loaded towards a locking position in which it holds the ball lock (3) in the engagement position. The locking sleeve (6) can be moved, counter to the spring-loading, to a release position in which the ball lock (3) is released, the movement of the locking sleeve (6) to the release position comprising both rotation about the longitudinal axis of the coupling and axial displacement parallel to this axis. According to the invention, the locking sleeve (6) comprises a main part (7) and an inner ring (8) which is rotatable in relation to the main part (7) and is arranged so as to interact with the ball lock (3) and also, by displacement parallel to the longitudinal axis of the coupling, be moved in order to allow the ball lock (3) to be transferred between the engagement position and the release position.

摘要： The present invention relates to a multi-tube coupling (1) consisting of at least two parallel coupling devices (3), each comprising matching first and second parts (5, 7) of the coupling for the transfer of fluid; the multi-tube coupling (1) consists of a base part (17) comprising the two first parts (5) of the coupling and a driving device (14) arranged for the displacement of the other parts (7) of the coupling of an array (9) of couplings in the direction of the base part (17). The driving device (14) consists of a central spigot (21), essentially centrally located between the coupling devices (3) in, the base part, and non-rotatably attached to the base part (17), which central spigot comprises a first electrical contact means (23); and a cam sleeve device (15) capable of rotating in the array (9) of couplings consisting of a screw-shaped cam surface (27) intended for engagement with devices (25) projecting from the central spigot (21).

摘要： The invention relates to a quick coupling for hoses or pipes for pressure media, especially for hydraulic media under high pressure. The coupling comprises a female part (1) and a nipple (2), said female part (1) having a displaceable valve element (4), which, in the decoupled state lies in sealing contact against the female part (1) by means of a sealing ring (5) and has an extension (7) with an enlarged end piece (8). The nipple has a displaceable valve element, which in the decoupled state, seals against the nipple (2) by means of a sealing ring (19). According to the invention, the valve element (4) of the female part (1) has, about its extension (7), an axially displaceable tube (9) which is urged by its spring (11) towards a position in abutment against the end piece (8). The tube (9) has essentially the same outer diameter as the valve elements (4, 18). The tube (9) is disposed, when the female part (1) and the nipple (2) are coupled together, to be inserted into the sealing rings (5, 19) to protect them.

摘要： The invention relates to a device for sensing and indicating the state of a medium in a conduit. The device comprises a sensor means (10) for sensing the value of a parameter of the medium in the conduit (8) and an indicator means (13) which is coupled to the sensor means and is intended to provide an indication which is dependent on the sensed value. The sensor means (10) is coupled into the conduit (8) and is provided with a channel which, when the sensor means is coupled in place, constitutes a portion of the conduit. The sensor means (10) has two electrodes which are electrically isolated from each other and extend into the channel. The indicator means is provided with or is coupled to a current source for applying a voltage between the electrodes of the sensor means (10) and is arranged to provide an optical and/or acoustic signal when the resistance of the medium exceeds a predetermined threshold value. According to the invention, a second sensor means in the form of a measuring probe (23) is coupled to an instrument (12) comprising the indicator means (13). The measuring probe (23), when immersed in a medium, senses a calibration value for calibrating the indicator means (13).

摘要： The invention relates to a coupling for coupling together hoses or pipes for pressure medium. The coupling comprises a coupling sleeve (1) and a nipple (2) insertable therein. The coupling sleeve (1) comprises a valve device for opening the flow-through of pressure medium as the nipple (2) is inserted to its engagement position and consists of a sleeve-shaped front part (5) and a sleeve-shaped rear part (6). According to the invention, the front part (5) is rotatable but axially essentially non-displaceably joined to the rear part (6) by means of a resilient lock ring (7). Furthermore, the valve device comprises a valve body (15) in the form of a sleeve, a valve seat (16) for cooperation with the valve body (15) and a blocking sleeve (14) for cooperation with the nipple (2) upon insertion thereof.
