  • Clutch and brake arrangement switchable by a compressible fluid, especially pneumatically
    Patent number: 5123508
    Abstract: A housing mounts an input shaft with a clutch flange thereon, and an output shaft with an annular friction member thereon to divide the housing clutch chamber into two separate operating chambers. A brake ring has a first friction face facing the friction lining of the friction member while the friction member has a second friction lining facing the clutch flange. The friction member is axially displaceable a limited amounted by a compressible fluid for controlling the movement of the friction linings axially between the linings and into engagement with one of the brake member and the clutch flange. Each of the clutch flange and the brake ring has an annular groove concentric to the coextensive axes of the shafts that opens to the axially adjacent friction lining.

  • Valve with presetting of the amount of throughflow
    Patent number: 4518147
    Abstract: A thermostatic valve assembly having a rotatably adjustable insert for varying the throttle resistance of the valve. The insert has a skirt with a spiral shape to effect a first varying cross section for the valve chamber in which the insert is disposed and the skirt also has an inclined section to effect a second varying cross section for the valve chamber.

  • Thermostatic valve
    Patent number: 4508263
    Abstract: The invention relates to a thermostatic valve assembly of the type in which a working element containing a vapor-liquid filling is housed in the temperature setting control knob. The assembly includes a housing having a projecting portion. There is a threaded adjusting connection between the knob and a base unit which is attachable to the housing projection portion. The invention is directed to specific constructions for attaching the base unit to the projection portion.

  • Thermostat attachment for a valve
    Patent number: 4508262
    Abstract: The invention relates to a thermostatic valve assembly of the type in which the working element containing the vapor-liquid filling is housed in the temperature setting control knob. A threaded adjusting connection between the knob and an axially moveable unit which controls the compression of the setting spring provides rugged and simple construction.

  • Remote control temperature sensor with expansible material
    Patent number: 4443120
    Abstract: The invention relates to a remote control temperature sensor having a capsule containing an expansible material and a capillary tube which connects the capsule to a radiator valve or the like. The temperature sensor has a housing in which the capsule in rotatably mounted and the housing is a wall where the temperature is to be monitored. The capillary tube is wound around the capsule and is dispensible therefrom any desired distance less than the length of the tube to the radiator valve to which the sensor is to be connected.
