The invention is directed to a divider block assembly made from one piece of material. Traditional divider blocks require modular sections so that piston alignment can be calibrated precisely. The current invention uses replaceable pistons and sleeves that are suitable for use at high fluid pressures. The use of these pistons also allows for a single, bodied, one-piece, metal divider body, rather than the conventional multiple block divider blocks, which allows for a more efficient manufacturing method and stronger, more reliable, and more efficient lubricant dispensing system. The use of any of these aspects separately can improve performance, and not all are required in every embodiment.

A conical member for a pump head of a liquid ring pump, the conical member including a body, the body defining a first body opening on a first end positioned to abut a first pump opening, a second body opening on the first end positioned to abut a second pump opening, and a port. The conical member further includes a radially outer lip arranged about the first end and positioned to abut a pump aperture. A sealing liquid introduction path is arranged to introduce sealing liquid to a working chamber, the sealing liquid introduction path arranged at least partially between the second body opening and an outlet, and a gas vent passage is arranged to vent gas from the working chamber, the gas vent passage arranged at least partially between the port and the first body opening.

The present disclosure relates to a mixing pump (10) for combining two or more substances. More specifically, the mixing pump (10) is adapted to combine controlled amounts of those substances so as to produce a mixture containing predetermined proportions of those substances. The mixing pump includes a chamber (23) lying in fluid communication with a first substance inlet (50), a second substance inlet (51) and a mixture outlet (52). The mixing pump (10) also includes a pumping member disposed in the chamber (23) and adapted to draw first and second substances from the first and second substance inlets (50,51) and to expel a mixture of those substances through the mixture outlet (52).

A liquid ring pump includes a planar port plate having first and second planar walls, a sidewall which defines a shaft receiving aperture, an inlet, and an outlet. An opening is formed in the port plate and includes an open end that extends through the sidewall and an open face that extends through the first planar wall. A rotor shaft is rotatable about a central axis and is positioned such that a portion of the rotor shaft extends into the shaft receiving aperture. An aperture is formed in the port plate and positioned substantially opposite the opening. The opening, a space defined between the rotor shaft and the sidewall, and the aperture, cooperate to define a channel that extends between a first side of the shaft receiving aperture and a second side of the shaft receiving aperture, wherein the channel is formed entirely coplanar with the port plate.

A compressor assembly having a housing with a number of sound control chambers. A method of controlling a sound level of a compressor assembly having a step of providing a plurality of sound control chambers. A method of controlling a sound level of a compressor assembly having a step of eliminating an operator's line-of-sight view to noise producing components of the compressor assembly. Sound level of a compressor can be controlled by separating the internal volume of a housing which encases at least a portion of a pump assembly to create sound control chambers and/or eliminating an operator's line-of-sight view to noise producing components of the compressor assembly.

A cryopump includes a housing, an electrical control unit which controls the cryopump, a purge valve provided on a passage between an external purge gas source and the inside of the housing, a rough valve provided on a passage between an external pump and the inside of the housing, a vent valve provided on a passage between the inside and the outside of the housing, and a Pirani gauge which measures a pressure inside the housing. The electrical control unit is connected to each of the purge valve, rough valve, vent valve, and Pirani gauge via a wire. Each of the wires is provided with a connector on the component side and a connector on the electrical control unit side. The connector on the component side is configured to be attachable to and detachable from the connector on the electrical control unit side.
