摘要:
A valve device for a compressed air supply system, includes a control chamber to which compressed air may be supplied, a control piston plate delimiting the control chamber, a control piston that is fixed to the side of the control piston plate facing away from the control chamber. The piston protrudes into a discharge valve chamber of a discharge valve, provided with at least one compressed air connection. A valve head delimits the discharge valve chamber, which can be pressurized with the force of a spring in the direction of a valve seat and which can be lifted from the valve seat by the control piston counter to the force of the spring in order to open the discharge valve. The control piston and a valve housing surrounding the control piston define at least two regeneration valve chambers of a regeneration valve having at least one compressed air connection. The at least two regeneration valve chambers are either separated from each other or connected together in accordance with the position of the control piston.

The invention relates to an air condition device consisting of recovery cells (1, 2), an inlet (3) and exhaust ducts (4) leading to and from a room, an inlet (5) and exhaust ducts (6) located at the other end of the device and leading to and from the outdoor air, the air flows in the air conditioning device being controlled by means of rotating deflectors (7, 8). The deflectors (7, 8) consist of baffles fixed to different control axes (9, 10) and rotating about their axes, the air openings (11, 12) provided in the deflectors being located altematingly at the same recovery cell (1, 2), where the air flow directions are reversed periodically.

A switch structure for a heating device having a passage formed within the main body of the structure, an air inlet, a main flame air outlet, a second air outlet and a thermocouple insertion hole connected to the passage being formed on the main body, and a manual control rod having a stopper being provided within the passage of the main body, two through holes being formed corresponding to the main flame air outlet and the second flame air outlet; characterized in that the main flame air outlet, the thermocouple insertion hole and the second flame air outlet have upward direction openings of similar direction, and the main flame air outlet and the air inlet are located on the same axis, and a stopper is suitably mounted between the main flame outlet and the air inlet, thereby the lighting rod of the switch, the thermocouple and the second air tube are extended in same direction to form an easy assemble, safe and stable switch for the heater.
摘要:
The present invention is concerned with a control device for medium flows for a regenerative heat exchanger. The device consists of a cell (7) divided into compartments (8) and acting as a heat exchanger, and at the ends of the cell, there are control means (11, 12) for guiding the medium flows alternatingly into the different compartments (8) of the cell (7). In prior art, unreasonably high capacities of actuating devices have been required for controlling the flows of media, and the control devices have increased the length of the heat exchanger considerably. These drawbacks are avoided if the control means consist of a slide (11, 12) displaceable transversely in relation to the partition walls (9) of the cell, the said slide (11, 12) being provided with openings (13) and with blocking members (14) between the openings for the purpose of alternatingly opening and closing connections between medium flow ducts (2, 3, 5, 6) and compartments (8) in the cell.
