A rubber mount for a reciprocating engine, includes two fluid filled working chambers which are axially defined by two elastically balloonable end walls and which are connected by at least two connecting passages in parallel arrangement. At least one of the connecting passages is a damping passage which is selectively closable by means of a valve. The damping passage is constructed in the form of a channel and is dimensioned so that when the reciprocating engine reaches idle speed, the enclosed fluid mass oscillates in a relative movement which is in phase with the engine vibrations, and has an amplitude which is larger than the amplitude of the vibrations of the reciprocating engine, multiplied by the ratio of the displacement cross-section of the balloonable end walls and the cross-sectional area of the damping passage. The rubber mount provides an improved damping of idle speed vibrations of a reciprocating engine.
