    Abstract: Pneumatic valve spring members (10) provide replacement for mechanical springs used to seat engine valves in internal-combustion engines. A valve guide (16) sits atop the engine head 40, allowing the valve stem (12) of valve (14) to pass and reciprocate therethrough. At the distal end of the valve stem (12), a valve retainer (30) is attached to the valve stem (12). The valve retainer (30) is spaced apart from the valve guide (16). A bellows seal flexibly interconnects the valve retainer (30) with the valve guide (16). Upper and lower isolators (52), (50) serve to hold an air cushion about the valve stem (12) adjacent the bellow seal (42). The air cushion (60) serves to maintain and store pressure, lifting the distal end of the valve stem (12) toward the rocker arm (36).

    Abstract: An improved air spring arrangement for an internal combustion engine having three valves per cylinder which are disposed in surrounding relationship to a spark plug. The air spring arrangement is formed by a recess formed in the cylinder head that encompasses each of the valve stems and an insert piece that is inserted into this recess and which defines the bores for the respective air chambers. The supply and relief passages for the air chambers are formed in the insert piece by drilled passages which have a V-shaped configuration to provide a more compact assembly and a less complicated cylinder head arrangement.

    Abstract: A valve assembly includes a valve having a head and a stem. The head is configured to seal against a valve seat. The stem has a distal end. A first piston radially extends from the stem of the valve and is enclosed within a housing. A second piston is fixed to the distal end of the stem and seals against the housing. A first chamber is defined by the first piston, second piston and the housing and receives a compressed gas and maintains a desired gas pressure. A spring device is disposed intermediate the first piston and the housing. During normal operation of the engine, the gas pressure within the first chamber seals the head of the valve against the valve seat with the spring device in a compressed arrangement and wherein during periods of insufficient gas pressure the spring device biases the valve to seal against the valve seat.

    Abstract: A poppet valve has a valve head and a valve stem. A piston is capable of reciprocating motion relative to a housing along a reciprocation axis. The piston has a valve-receiving portion for receiving therein an end portion of the valve stem. A cotter secures the valve stem to the piston. A cap is disposed around the valve-receiving portion. A cap lateral portion extends away from the cap end portion in the direction of the valve head. The valve-receiving portion is held between the cap end portion and the cap lateral portion in a direction parallel to the reciprocation axis. At least part of the cap lateral portion is angled toward the reciprocation axis. The part of the cap lateral portion is closer to the reciprocation axis than at least part of the valve-receiving portion. A method of assembling a valve assembly is also described.
