LOW POWER CONSUMPTION PISTON COMPRESSOR Russian patent published in 1998 - IPC

FIELD: transport engineering; production of compressed air for vehicles. SUBSTANCE: piston compressor has suction valve plate 9 installed for linear displacement and setting into working position overlapping suction valve hole 11 and opening discharge valve hole 13. Plate can be shifted in idling position at which suction valve hole 11 is partially opened and discharge valve hole 13 is partially closed. Guide surfaces 17, 17' passing in parallel with direction of movement are installed on both ends of suction valve plates 9 to provide reliable direction of plates 9. Guide surfaces engage in movement with corresponding surfaces on valve plate 1 or on members coupled with this plate. Piston drives 27 are installed to provide displacement of suction valve plate 9. Axis of piston drives is pointed in direction of displacement. Piston drives are connected with suction valve plate 9 by means of pin 24. EFFECT: enlarged operating capabilities. 7 cl, 2 dwg
