摘要:
A single-piece piston for use in a pneumatically-activated pump to meter a predetermined amount of lubricant or other liquid. The piston has a grooved end that includes a head portion and a circumferentially-disposed angled channel for containing a sealing member such as an O-ring. An adjacent stem section includes a longitudinally-disposed channel that is in fluid-flow connection with the angled channel. The piston is disposed within a chamber of the body of the pump. Lateral movement of the piston within the body causes the sealing member to shift and block and unblock the end of the longitudinal channel which allows liquid from a liquid chamber to flow into a slot and to a pump chamber adjacent to the head of the piston's grooved end. The piston operates in association with an assembly for regulating the amount of liquid metered by the pump, a valve assembly for evacuating the liquid from the pump chamber into and through an outlet fitting, and a mechanism for regulating the flow of air into the outlet fitting to atomize the liquid.

A single-piece piston for use in a pneumatically-activated pump to meter a predetermined amount of lubricant or other liquid. The piston has a grooved end that includes a head portion and a circumferentially-disposed angled channel for containing a sealing member such as an O-ring. An adjacent stem section includes a longitudinally-disposed channel that is in fluid-flow connection with the angled channel. The piston is disposed within a chamber of the body of the pump. Lateral movement of the piston within the body causes the sealing member to shift and block and unblock the end of the longitudinal channel and an aperture in the angled channel, which allows liquid from a liquid chamber to flow into a central bore in the piston and to a pump chamber adjacent to the head of the piston's grooved end. The piston operates in association with an assembly for regulating the amount of liquid metered by the lubricator, a valve assembly for evacuating the liquid from the pump chamber into and through an outlet fitting, and a mechanism for regulating the flow of air into the outlet fitting to atomize the liquid.

A pneumatically-operated pump is provided that includes a body having a central bore with a liquid chamber for a slidable piston injector, a chamber for a removable reservoir, and an inlet and outlet for a gas. A priming conduit carries liquid from the reservoir mounted on the body to the injector in the liquid chamber which injects the liquid into a liquid line coupled to a fitting on the pump. The liquid line carries lubricant or other liquid from the pump (e.g., air tool lubricator) to an air tool or other article. A priming pump is mounted on the body and is capable of delivering a predetermined amount of liquid from the reservoir to the liquid chamber. The priming pump is used to fill the liquid line with liquid.

Embodiments provide methods, apparatuses, and systems for monitoring and communicating power faults. In various embodiments, a first voltage and a second voltage, both associated with an adapter, are monitored. The first voltage may provide system power and the second voltage may identify a capacity of the adapter. In response to detecting a voltage change, a power failure event may be communicated.

A method and apparatus for the selection of oral care chemistries by a consumer from a plurality of available options. An oral care selection advisor first requests information from a consumer regarding their oral care preferences. The oral care selection advisor then selects a classification of chemistries from among at least two available classifications corresponding to those oral care preferences. The information is then displayed from the oral care selection advisor identifying at least one chemistry within the selected classification, allowing the consumer to identify the chemistries corresponding to the consumer's oral care preferences.

Certain exemplary embodiments can provide a system that comprises a valve coupled to a water supply to a showerhead. The valve is constructed to turn a water flow on and off to the showerhead. The system comprises a first switch mounted outside of a shower stall. The first switch can be constructed to, responsive to a first user action, cause the valve to turn the water flow on.

An explosion proof motor including a stationary assembly and a rotatable assembly is described. The stationary assembly includes a stator that defines a stator bore. The rotatable assembly includes a rotor and a rotor shaft extending substantially axially through the stator bore. The explosion proof motor includes a frame configured to at least partially surround the stator. The frame defines an interior and an exterior of the motor. The explosion proof motor also includes at least one end shield positioned at an end of the frame and a bearing cap positioned proximate to the interior side of the end shield. The explosion proof motor also includes a flame path gap defined between the end shield and the bearing cap. The flame path gap includes at least one section that extends substantially parallel to the rotor shaft.
