Abstract

A compressor ( 10 ) for compressing air for a compressed air system of a motor vehicle has a cylinder housing ( 14 ) and a cylinder head ( 16 ) connected thereto. A compressor piston is moveable in oscillation up and down in a cylinder in the cylinder housing ( 14 ). A lamella ( 34, 36 ) is received in a depression ( 38 ) in an underside ( 30 ) of the cylinder head ( 16 ) facing the compressor piston. The delivery rate of the compressor ( 10 ) can be regulated by closing or opening a control channel ( 60, 60 ′) in the cylinder head ( 16 ) via the lamella. A bearing end ( 44 ) of the lamella ( 34, 36 ) is hinged in a pivotably guided manner on a bearing contour ( 54 ) of this depression ( 38 ). As a result, a separate bearing journal for pivotable mounting of the lamella ( 34, 36 ) on the cylinder head ( 16 ) may be omitted.

Claims (15)

1. A compressor ( 10 ) for compressing air for a compressed air system of a motor vehicle, the compressor comprising

a cylinder housing ( 14 ),

a cylinder head ( 16 ) connected thereto,

at least one cylinder in the cylinder housing ( 14 ),

at least one compressor piston moveable in oscillation up and down in the at least one cylinder in the cylinder housing ( 14 ), and

at least one lamella ( 34 , 36 ) received in at least one depression ( 38 ) in an underside ( 30 ) of the cylinder head ( 16 ) facing the at least one compressor piston,

wherein a delivery rate of the compressor ( 10 ) is regulated with little loss by closing or opening at least one control channel ( 60 , 60 ′) in the cylinder head ( 16 ) via the at least one lamella, and wherein the at least one lamella ( 34 , 36 ) has a bearing end ( 44 ) hinged in a pivotably guided manner on a bearing contour ( 54 ) of the depression ( 38 ).

2. The compressor according to claim 1 , wherein the bearing end ( 44 ) of the at least one lamella ( 34 , 36 ) and the bearing contour ( 54 ) of the at least one depression ( 38 ) in the cylinder head ( 16 ) are formed at least partially circular.

3. The compressor according to claim 1 , wherein the bearing end ( 44 ) of the at least one lamella ( 34 , 36 ) and the bearing contour ( 54 ) of the at least one depression ( 38 ) of the cylinder head ( 16 ) engage in each other by form fit at least locally.

4. The compressor according to claim 1 , wherein the at least one lamella ( 34 , 36 ) comprises an actuating portion ( 48 ) at an actuating end ( 46 ) directed away from the bearing end ( 44 ).

5. The compressor according to claim 4 , wherein the actuating portion ( 48 ) is formed approximately T-shaped and comprises two approximately semicircular leg ends ( 72 , 74 ) arranged opposite each other at the short T-legs, and wherein an actuating pin ( 50 ) for mechanical coupling to an actuator ( 56 ) is formed or attached approximately centrally between the two leg ends ( 72 , 74 ).

6. The compressor according to claim 5 , wherein the bearing end ( 44 ) and the actuating portion ( 48 ) of the at least one lamella ( 34 , 36 ) are connected together via a valve portion ( 52 ) which is arcuate on both sides.

7. The compressor according to claim 1 , wherein in an unloaded running operating position of the at least one lamella ( 34 , 36 ), a valve portion ( 52 ) of the at least one lamella ( 34 , 36 ) at least partially opens the at least one control channel ( 60 , 60 ′) in the cylinder head ( 16 ).

8. The compressor according to claim 1 , wherein in a loaded running operating position of the at least one lamella ( 34 , 36 ), a valve portion ( 52 ) of the at least one lamella ( 34 , 36 ) completely closes the at least one control channel ( 60 , 60 ′).

9. The compressor according to claim 1 , wherein the at least one lamella ( 34 , 36 ) has a material thickness ( 62 ) that is approximately constant across the entire at least one lamella, and wherein the material thickness ( 62 ) is smaller than a depth ( 64 ) of the at least one depression ( 38 ) in the underside ( 30 ) of the cylinder head ( 16 ).
