Abstract:
A pump housing ( ) has a fan guard ( ) secured to the end of the housing by four crescent-shaped tabs ( ) fitting into four crescent-shaped cast-in recesses ( ) of the housing ( ) and ears ( ) of the tabs ( ) fitting into cast-in holes ( ) in the housing ( ). The ears ( ) and boles ( ) on opposite sides of the housing ( ) are aligned along a common axis ( ). The ears ( ) are tapered at their leading ends ( ) and squared off at their trailing ends ( ), and the guard ( ) has a radial projection ( ) that fits into an opening in the housing ( ).
A nebulizer pump includes an axial cylinder and piston arrangement and an electromagnet having a stator and an armature that drives the piston to reciprocate within the cylinder. The pump housing has a unitary partition defining an exhaust chamber in combination with the valve head that isolates air at the intake port from air at the exhaust port. The entire assembly can be clamped together by the housing or clamped separately and isolated from the housing by coil springs.
Clam Shell Pump Housing Defining Passageways And A Sealed Pressure Or Vacuum Chamber
A pump has a motor pump unit enclosed by clam shell housing sections. The pump moves a working fluid through the housing to an outside load. Each section has intake walls defining a portion of an intake chamber and outlet walls defining a portion of an outlet chamber. The intake walls of each section seal against one another to define a sealed intake chamber which is in communication with the intake port of the pump unit, and the outlet walls of each section seal against one another to define a sealed outlet chamber which is in communication with the outlet port of the pump unit.
A pump () has a clamshell housing () with walls () that come together and seal to create chambers () which contain a pressure difference relative to ambient pressure.
A compact pump has a uni-body, or alternately a two-part, housing of self-skinning foam construction for superior noise and vibration reduction, such as needed for medical nebulizer applications. The uni-body foam housing is formed by molding the housing around a pump assembly having special features designed to shield and space apart moving or sensitive internal components of the pump assembly from the foam during the insert molding process. The alternate two-part foam housing is assembled using a union ring having multiple barbed pins that fit into openings in mating faces of the two housing sections.

Abstract:
A ball joint connector is provided for linking a showerhead to a water supply pipe. The connector has an internal venturi that draws air into the connector to aerate water being provided to the showerhead. A flow control member is disposed in a fluid pathway connected to the venturi, preventing spraying or leaking out the air inlet, while reducing noise associated with the air induction.
