Inhalation therapy device compressor

Inhalation therapy device compressor for an inhalation therapy device having

• a housing with a first compression space and a second compression space;
• a gas inlet means for the inflow of a first gas into the first compression space;
• a gas outlet means for the outflow of the first gas from the first compression space, and connected to the inhalation therapy device to generate a pressure medium flow;
• the second compression space being isolated from gas communication with the first compression space by a compression means, that closes off the first compression space in such a manner that, on moving the compression means, the first gas is conveyed into the first compression space via the gas inlet means and out of the first compression space via the gas outlet means;
• a movement means integrally disposed in the second compression space, comprising an eccentric plate driven by an electromotor and a connecting rod connected between the eccentric plate and the compression means, for moving the compression means backwards and forwards;
• a single gas passage opening, in gas communication with the second compression space, through which a second gas flows out from the second compression space when the compression means reduces the second compression space and through which the second gas flows into the second compression space when the compression means enlarges the second compression space, so that bi-directional pressure variations, resulting from the movement of the compression means in the second compression space, are applied to the second gas and pass through the gas passage opening;
• and
• a hose line, provided at the gas passage opening, with which the pressure variations from the movement of the compression means are applied to the inhalation therapy device and are superimposed upon the pressure medium flow.
