A choke valve, which comprises a housing wherein a choke duct extends. Two connection ports of the choke duct render possible the connection of means for the supply and removal of driving fluid. A choke member cooperates with the choke duct and is able to be set for the regulation of the flow rate. One of the connection ports is provided on the choke member, the adjoining portion of the choke duct extending through the choke member. It is in this manner that one connection side of the valve is also the adjustment side of the choke valve, something which reduces the amount of space for the fitting thereof.

An electropneumatic control device having a plurality of valves, each valve being associated with at least one electrically actuatable valve drive. Each valve drive has integrated therein its own bus communication unit and is coupled to a bus line for communication with a central control unit. Actuating control signals are supplied from the central control unit for controlling each of the plurality of valves integrated therein. The valve drives may also include electrical contacts for piercing an insulating sheath of the bus line to make electrical connection with control wires within the bus line. The electropneumatic control device described above reduces design complexity.

The invention proposes a control device for multiway valves. It comprises two adjacently arranged solenoid means, which are respectively associated with a valve member to be driven. Each solenoid means comprises a coil. Outside the coils there is a yoke device for conduction of the magnetic fields, which are comprised in a yore part, which is associated with coils so that it may be pervaded by the magnetic fields of both coils. It is in this manner that an extremely compact design is rendered possible.

A spool valve having a valve housing with an internal spool receiving space, in which a valve spool is arranged. A plurality of sealing rings are arranged in axial sequence. Such sealing rings are retained in holding recesses, which are formed integrally with the valve housing. The valve housing is itself longitudinally divided and is composed of a plurality of housing parts which respectively constitute a wall section, extending for some distance in the peripheral direction, of the spool receiving space including the associated peripheral sections of the holding recesses. It is in this manner that the sealing rings may be inserted into the spool receiving space without any difficulty in the separated condition of the housing parts, whereafter the housing parts only have to be fitted together.

A linear drive which has a housing with a longitudinal slot. A drive part able to be longitudinally moved in the housing is connected by the aid of a link part, running in the longitudinal slot, with a guide part, which is guided for motion on a longitudinal guide arranged outside the housing. As a longitudinal guide a rod guide is provided, which has at least one guide rod adjacent to the housing and spaced from it radially. The guide rod is exposed along its guide stroke and has the guide part encircling it. There is therefore the possibility of accurate guiding of the moving unit without being affected by any tendency of the housing to splay outwards. The costs of manufacture are low.
摘要:
A sealing arrangement for valve has at least one sealing ring, which has a substantially U-like cross section of its housing ring, which is made up of a plurality of parts which are permanently connected together. In the ring space of the housing ring a single, integral sealing element is mounted so as to be able to yield radially and with the housing ring it constitutes a component which may be uniformly handled. A sealing part thereof extends out of the housing opening of the ring space. A sealing ring of this type may be locked in valve housings in order to provide a sealing action between the valve housing and the moving valve piston. The design of the sealing rings makes them suitable for robotized assembly.

The flow regulating valve for pneumatic or other fluids comprises a housing with two valve spaces separated from each other by a partition and each having a port opening into them. The two valve spaces are able to be connected with each other by a cutout or transfer port in the partition. In one valve space there is a rotary valve member which covers the transfer port to a greater or lesser extent in accordance with the amount it is turned. On adjusting the position of the rotary valve member the effective size of the transfer port may be varied to control the flow of the fluid between one valve space and the other.

The present invention provides a protective device for a working member, such as the piston rod of a piston and cylinder actuator, which is arranged at least partly in a receiving member and is able to be moved and more especially slid, along a curved or straight path so that it projects to a greater or lesser extent out of the receiving member. The device is provided with a plurality of sleeve-like guard sections which surround the working member projecting out of the receiving member along the full length of the working member so that whatever the position of the latter any two adjacent guard sections overlap each other and are able to be slid in relation to each other, one of said guard sections being stationarily arranged on the receiving member and another guard section being arranged on the working member so as to move therewith so that in accordance with the actual axial extent of the part of the member to be protected the sections are telescoped into each other to a greater or lesser extent.
摘要:
A valve arrangement comprising several valve units placed in rows side by side in the a direction in a common row defining plane. Each valve unit comprises a base plate with supply and venting ducts extending therethrough and two mutually parallel spool receiving spaces each having a valve spool. The supply and venting ducts run in the partition, placed between the two spool receiving spaces, of the base plate and simultaneously communicate with the two spool receiving spaces. Such a valve arrangement may be manufactured with compact dimensions and have high flow through rates.
