An improved check valve assembly of the type having a relatively flexible disc member retained between relatively rigid inflow and outflow housing portions. The inflow and outflow housing portions are removably threadably interengaged to permit serviceability of the check valve and the relatively flexible disc member has a generally perpendicular stem extending into the bore of one of the housing portions to avoid misalignment of the disc with the housing. A tongue and groove means circumferentially seals the housing portions together by deforming to a common taper angle between the tongue and groove to provide sealing therebetween.

An apparatus for providing bleed air to exit an air outlet fitting where an air hose is connected to a turbine housing to cool the turbine and outlet fitting. The bleed air is directed through longitudinal channels outside the air hose and to an air diffuser collar where it is deflected to exit the apparatus radially.

It has become necessary to provide warning tags and labels on equipment such as point sprayers to protect the operators so that they will not be injured and to protect the manufacturer so that it will not be sued for product liability. Often such warning labels and tags have been attached to the packages or cartons in which the apparatus is shipped and they can become separated from the equipment so that a user does not see the warning. The present invention provides an integrally molded-in place warning label which is attached to an electric cord of an appliance, such as a paint sprayer which is molded to the electrical power cord and which can be molded to the cord at the same time that a stress release and a power connector plug are molded to the cord. The warning label may be made of the same material as a strain release device and may be made of a tough resilient material so that it cannot be torn or separated from the power cord once it has been molded. The mold may be provided with dropin type face which prints such that during molding the warning is formed on the warning label in a three-dimensional form so that it will be readily available each time the tool or machine is to be used.
