Gaseous fluid compression device

An apparatus for compressing gas-phase fluid comprising:

• a housing having a wall;
• a non-motional stator having a base plate and a helical wall extending from one side of the base plate;
• a motional orbiter having a base plate and a helical wall extending from the base plate, the base plate of the stator and the base plate of the motional orbiter disposed wherein the wall of the stator and the wall of the motional orbiter engage each other to define closed working chambers, volumes and positions of the working chambers being changed in response to motion of the motional orbiter;
• a counter-pressure area defined between the wall of the housing and the motional orbiter;
• a guide device having an opening formed in the base plate of the motional orbiter and a pin fixedly coupled to and protruding from the housing, the pin engaging into the opening;
• and a sliding element disposed between the wall of the housing and the motional orbiter and fixedly coupled to the wall of the housing, wherein the sliding element is provided for compensation of friction generated by relative motion between the wall of the housing and the motional orbiter, wherein the pin is pressed into an opening formed in the sliding element, wherein the sliding element is pressed into and coupled to the housing by a force-fit, wherein the housing comprises a recess having a side and a base surface, the side of the recess is fitted and coupled to an outer jacket surface of the sliding element so that a first circular ring surface of the sliding element is fixed in contact with the base surface of the recess.
