Abstract: A throughflow rate limiting device with a spring-loaded valve body which is disposed upstream of a cross-sectional constriction in a flow duct so as to be axially slideable between a first and a second position. The valve body is loaded by a spring in the direction of the first position, and for a given pressure gradient throughflow in the first position is greater than in the second position. The cross-sectional constriction may be bypassed by at least one bypass line which branches off from the flow duct upstream of the cross-sectional constriction and rejoins the flow duct downstream of the cross-sectional constriction. In order to achieve small flow resistance in the open state and abrupt switching, the valve body has the shape of a double cone.

Abstract: A guide for use in a vehicle engine having an engine block, cylinder head, and a cylinder head gasket. The guide comprises a valve lifter retention portion, a push rod retention portion in communication with the valve lifter retention portion via one or more apertures, and an alignment and attachment portion extending from the push rod retention portion and configured to be retained by contact with the cylinder head gasket.
