Abstract
A dual direction vacuum apparatus for creating vacuum and purging obstructions from a vacuum port of the apparatus. The apparatus provides a housing having an air passageway, wherein the air passageway has a first end and a second end. A vacuum pressure inlet is formed in the housing and is adaptable to receive pressurized air from a pressurized air source to create vacuum in the vacuum port and establish a vacuum mode. A purge pressure inlet is formed in the housing and adaptable to receive pressurized air from a pressurized air source to direct pressurized air toward the vacuum port to establish a purge mode and dislodge any obstructions from the vacuum port.
Claims20
A dual direction vacuum apparatus, comprising:
- a housing having an air passageway, wherein the air passageway has a first end and a second end, wherein the housing has an aperture extending therethrough;
- a vacuum pressure inlet formed in the housing and adaptable to receive pressurized air from a pressurized air source, the vacuum pressure inlet in communication with the air passageway;
- a vacuum nozzle partially disposed in the aperture within the housing, such that a venturi jet is defined between the vacuum nozzle and the housing, wherein pressurized air from the vacuum pressure inlet passes through the venturi jet and is directed toward the second end of the air passageway to create a vacuum in the first end of the air passageway when the apparatus is in a vacuum mode;
- a purge pressure inlet formed in the housing and adaptable to receive pressurized air from a pressurized air source, the purge pressure inlet in communication with the air passageway;
- and
- a purge nozzle partially disposed in the aperture within the housing, such that the purge nozzle provides communication between the purge pressure inlet and the air passageway, wherein pressurized air from the purge pressure inlet is directed toward the first end of the air passageway to dislodge obstructions in the first end of the air passageway when the apparatus is in a purge mode.

A dual direction vacuum apparatus, comprising:
- a housing having an aperture extending therethrough with a first end and a second end, and an air passageway extending through and along a longitudinal axis of the housing, wherein the aperture has an hour glass shaped necking portion defining a portion of the air passageway;
- a vacuum nozzle having a tapering first end disposed within the first end of the aperture in the housing, wherein the tapering first end is adjacently positioned in the hour glass shaped necking portion of the air passageway within the housing to form a venturi jet between the tapering first end of the vacuum nozzle and the hour glass shaped necking portion of the housing, and the vacuum nozzle having an air passageway extending through the vacuum nozzle and in communication with the air passageway of the housing;
- a purge nozzle having a tapering first end disposed within the second end of the aperture of the housing and adjacently positioned in the hour glass shaped necking portion of the aperture within the housing to form a purge passageway between the tapering first end of the purge nozzle and the hour glass shaped necking portion of the housing, and the purge nozzle having an air passageway extending through the purge nozzle and in communication with the air passageway of the housing and the vacuum nozzle;
- a vacuum pressure inlet formed in the housing and adaptable to receive pressurized air from a pressurized air source, wherein the vacuum pressure inlet communicates pressurized air from the pressurized air source to the venturi jet, wherein a vacuum is created in the air passageway of the vacuum nozzle when pressurized air passes through the venturi jet and into the air passageway of the housing and the purge nozzle;
- and
- a purge pressure inlet formed in the housing and adaptable to receive pressurized air from a pressurized air source, wherein the purge pressure inlet communicates pressurized air from the pressurized air source to the purge passageway and through the air passageway of the vacuum nozzle to dislodge obstructions in the air passageway of the vacuum nozzle.
