Abstract
A valve apparatus comprising a valve housing defining a valve bore and a valve chamber through which an inflow pipe and an outflow pipe communicate at right angles with each other. A valve stem is disposed in the valve chamber to be axially reciprocable. The valve stem carries an elastic packing fitted on a head portion of the valve stem, the elastic packing being movable into and out of pressure contact with a valve seat defined at a connection between the valve bore and the valve chamber. A support plate is mounted at an inlet of the valve bore, which support plate defines flow-through openings and a non-circular support bore. The valve stem includes a forward portion having a sectional shape fitting with the non-circular support bore and extending into the non-circular support bore.
