Abstract
Abstract A compressed air dehumidifier comprises two containers having an adsorbent therein and having connections for the supply and delivery of air. Valve structure are provided for connecting the containers alternatingly one at the time into a compressed air system for passing air to be dehumidified through the connected container. Apparatus is provided for choked bleeding of a fraction of the dehumidified air from the connected container to the other container. A control valve (16-19) for accomplishing said alternatingly connection and for discharging said air fraction from said other container to the surrounding air includes a valve body (19), which has two recesses (37) for locking engagement one at the time with an axially movable valve stem (26) in order to hold the valve body against either one of two seats (16, 17), between which the valve body is movable.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A compressed air dehumidifier, comprising two containers (2A, 2B) having an adsorber (9) therein and having connections for the supply and delivery of air, valve means (11-13) for connecting the containers alternatingly one at the time into a compressed air system for passing compressed air to be dehumidified through the connected container, means for choked bleeding of a fraction of the dehumidified air from the connected container to the other container, and a control valve (16-19) for accomplishing said alternatingly connection and for discharging said air fraction from said other container to the surrounding air, said control valve including a valve body (19) movable between two seats (16, 17) and a valve stem (26) axially movable either to mechanically lock the valve body against one seat or to release it therefrom for movement to the other seat, characterized in that the valve body (19) has two recesses (37) for locking engagement one at the time with the valve stem (26) in order to hold the valve body against either one of the seats (16, 17).
Claim 2
Dependent Claim
175 words
A compressed air dehumidifier, comprising two containers (2A, 2B) having an adsorber (9) therein and having connections for the supply and delivery of air, valve means (11-13) for connecting the containers alternatingly one at the time into a compressed air system for passing compressed air to be dehumidified through the connected container, means for choked bleeding of a fraction of the dehumidified air from the connected container to the other container, and a control valve (16-19) for accomplishing said alternatingly connection and for discharging said air fraction from said other container to the surrounding air, said control valve including a valve body (19) movable between two seats (16, 17) and a valve stem (26) axially movable either to mechanically lock the valve body against one seat or to release it therefrom for movement to the other seat, characterized in that the valve body (19) has two recesses (37) for locking engagement one at the time with the valve stem (26) in order to hold the valve body against either one of the seats (16, 17).
Claim 3
Dependent Claim
64 words
A dehumidifier according to claim 1, characterized in that the valve body (19) is substantially cylindrical with spherical or conical ends for cooperation with the seats (16, 17), that the valve body between the recesses (37) is provided with a shallower groove (38), and that each recess has a shape corresponding to that of the tapered or pointed end of the valve stem (26).
Claim 4
Dependent Claim
71 words
A dehumidifier according to claim 1, characterized in that the valve stem (26) is provided with an annular flange (34), which at its outer periphery sealingly cooperates with the inner periphery of a sealing ring (33), when the valve stem is retracted from the recesses (37) in the valve body (19) but otherwise leaves a discharge passageway open through the sealing ring and a venting channel (35) to the surrounding air.
Claim 5
Dependent Claim
56 words
A dehumidifier according to any of the preceding claims, characterized in that a control compartment (24, 25) with an inlet (39, 40) is provided on either side of a diaphragm (23) connected to the valve stem (26) and that a spring (29) acting on said diaphragm may be arranged in either one of said two compartments.
