摘要： A valve for a cryogenic-fluid device has a valve seat, separate from the valve housing and of a different material, secured to the housing by shrink-fitting into a recess thereof. The readily replaceable seat has a high structural strength and preferably has been subjected to an anodizing treatment. The valve seat projects axially into the path of fluid passing through the nonclosable valve port. The valve housing is made of easily weldable materials, e.g., aluminum and aluminum alloys, and flanges for pipe connections are welded to the valve housing.

摘要： A piston pump having an intake valve whose valve member is approached by the pump piston. The piston magnetically attracts the valve member during the intake stroke to overcome the force of the spring biasing the valve member into its closed position.

摘要： A piston pump for conveying a fluid includes a cylinder which is not flanged to the pump casing, but rather is inserted in the pump casing and is retained in the longitudinal direction by a pretensioned spring. A seal is arranged between the cylinder jacket and the pump casing in order to seal the pressure side with respect to the suction side of the piston pump. An extremely compact piston pump results therefrom, suitable, in particular, for use in the low-temperature range due to very low cold losses.

摘要： A valve for controlling the admission of gas to a cylinder of a piston-type machine, or for the discharge of gas therefrom, comprises a magnetic armature shiftable between a pair of magnetic poles formed to receive the armature with minimal radial play and with a predetermined air gap from the attracting pole in the energized condition of the coil. The energizing circuit includes an inductive proximity switch which is triggered without engagement by a metal formation on the crankshaft and applies its signal to a pulse former generating a steep-flank pulse triggering a timer to produce two rectangular voltage pulses of different durations. These pulses are applied to a gating circuit which produces a stepped signal with a high initial amplitude which is amplified and applied to a power converter energizing the coil with a corresponding current waveform. A monitoring circuit responds to deenergizing the coil to drain residual magnetism from the pole piece to enable a spring to rapidly close the valve.

摘要： The proposal is for a rotary piston engine with a displacement element 12 which has a helical groove 17 and rolls along the internal diameter of a cylinder 2 due to an eccentric fitted on a drive shaft 5. The rotary piston engine furthermore has a helix 11, the external diameter of which always rests on the cylinder 2 and the internal diameter of which forms a seal in every position of the eccentric on the base of the groove of the displacement element 12. Owing to the inclination of the groove 17 in the displacement element 12 and to the movable insertion of the helix 11 into this groove 17, it is possible, when the drive shaft 5 is rotated, for a fluid to be delivered from an inlet chamber a into a delivery chamber b.
