Abstract
Electric compressor comprising a compression cylinder and the respective head, a valve plate arranged between the head and the body of said cylinder and provided with a gas inlet opening, a silencer arranged at the inlet side of said opening and comprising an elongated portion with an aperture adapted to fit in with said opening. The head is provided externally with a concave recess which is laterally open towards the inner cavity of the compressor, said elongated portion of the silencer being firmly housed in said recess so that the aperture engages the opening in the valve plate in an air-tight, sealed manner. In said recess there is provided a hollow space between said elongated portion and the outer wall, said hollow space being adapted to accommodate an elastic element for locking the silencer in place.
