  • Compressed gas apparatus
    Patent number: 4955994
    Abstract: An air dryer of the type fitted with a purge valve 92 is fitted with an input cut-off valve (81) which closes when the purge valve is opened in order that the compressor output line 2 is not vented thereby maintaining compressor and/or turbo charger pressure during off-load conditions.
    Type: Grant
    Filed: January 29, 1988
    Date of Patent: September 11, 1990

  • Spring force actuators
    Patent number: 4907496
    Abstract: A spring force actuator comprising a housing, an output member axially moveable in the housing, a spring captive between the member and the end wall of the housing. The actuator further comprises an axially located screw-threaded wind-off element operable to apply an opposing force to the spring between the output member and the end wall. The wind-off element is threadedly cooperable with a nut which is non-rotationally captive in an externally accessible recess of the end wall.

  • Fluid injector devices
    Patent number: 4442957
    Abstract: An antifreeze injector device for compressed air braking systems has a closed compressible bellows or compensatable rubber cylinder, the inside of which communicates with liquid to be injected and the exterior of which is subject to actuation pressure. The effective area subject to the actuator pressure being greater than that subject to the liquid to enable operator to inject into a reservoir of elevated pressure but to avoid the use of sliding pistons.

  • Fluid seal element for compressed air filter
    Patent number: 4345767
    Abstract: An annular fluid seal element for use in an air drier or condenser has a section which provides lips which, when assembled to an aperture in a member, lie to either side of the aperture, one shorter lip acting as a compression seal between the latter member and another and the other longer lip sealingly covering a plurality of passages on the member but permitting fluid flow via the passages in the event of pressure build-up inside them.
