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.

An isolation valve assembly is provided that includes a valve body having an inlet and an outlet, a sealing body disposed within an interior cavity of the valve body, and an actuatable closure element disposed within the valve body. The sealing body comprises a channel extending between a first opening on a surface of the sealing body and a second opening on an opposite surface of the sealing body. The sealing body is rotatable between a first position permitting gas flow from the inlet to the outlet of the valve body via the channel, and a second position preventing gas flow from the inlet to the outlet of the valve body. The actuatable closure element is configured to retain the sealing body stationary in the first position or the second position.
