A valve having a housing, a solenoid arranged in the housing, a pin movable by the solenoid, a cup-shaped piston connected to the pin, a seal arranged in the base region of the piston that interacts with a valve seat, and a seal arranged in the region of the open end of the piston and seals the piston from the housing. The seal interacting with the valve seat has an outer diameter, which approximately corresponds to the outer diameter of the seal at the open end of the piston.

A valve with a valve housing having a first connection along a first axis, a second connection along a second axis and a valve seat which surrounds the first connection arranged in the flow path of a flow chamber. A valve part is displaceable along a movement axis such that a closure surface can interrupt and release the flow path. A motorized drive unit to displace the valve part having a valve rod with a contact element, the drive unit has a guide mechanism with an actuating element configured to rotate about an actuating axis defining an outer track. The distance of the track from the actuating axis is adjustable by a rotation of the actuating element about the actuating axis. A rotation of the actuating element of the valve part is movable so that the interruption or release of the flow path can be provided thereby.
