  • Patent number: 4376472
    Abstract: In a cylinder piston device, a piston unit is fixed to a piston rod member within a cavity defined by a cylinder member. The piston unit is provided with a piston ring supporting face, which is directed substantially in a radially outward direction towards the inner circumferential surface of the cylinder member. A piston ring member with a radially inner circumferential face and a radially outer circumferential face is supported by its radially inner circumferential face on said piston ring supporting face and engages by its radially outer circumferential face the inner circumferential surface of the cylinder member. The piston ring member is provided with at least one radially inward directed projection extending in the radially inward direction beyond the radially inner circumferential face, the projection axially engaging a securing face of the piston unit, and the securing face extending radially inward of the piston ring supporting face.

  • Patent number: 4271869
    Abstract: A hydropneumatic assembly particularly for use as a pressure reservoir in a shock absorber includes a housing with a diaphragm operatively mounted within the housing to define therein a liquid chamber on one side of the diaphragm and a gas chamber on the opposite side thereof. The liquid chamber is defined between an inner wall of the housing and the diaphragm and the diaphragm is arranged to be pressed against the inner wall under the influence of gas pressure within the gas chamber. Damping liquid for a shock absorber flows into and out of the liquid chamber to an opening provided in the inner wall of the housing and, by a special feature of the assembly, ducts are defined between the inner wall of the housing and the diaphragm, with the ducts being directed to extend toward the opening through which liquid flows into and out of the liquid chamber.

  • Patent number: 4215486
    Abstract: Circuit for controlling the program timer of a laundry dryer as a function of the moisture-dependent resistance of the laundry. A storage capacitor charged from a d-c voltage source together with laundry resistance resulting from wet laundry bridging two electrodes and resistance determine the duty cycle or frequency for an oscillator. The output of the oscillator is fed to a filter and from there as one input to a comparator. A reference value setter is fed to another input of the comparator. The output of the comparator is functionally connected to the program timer. This circuit arrangement makes possible measurement of low residual moisture values in the laundry and thereby permits the start of the post-drying phase without heating on reaching this low residual moisture value.
