Abstract: An overhung external spur gear positive displacement pump for hot oil or deep fryer applications is disclosed. The external gear pump includes a casing that includes a through bore for accommodating a drive shaft that leads to a pump chamber that accommodates a drive gear and a driven gear. The casing further includes a recess connected to the pump chamber for accommodating a stationary pin. The casing also includes a proximal end coupled to a prime mover and a distal end coupled to a head. The gears are enclosed in the pump chamber by the head. The stationary pin is accommodated within the driven gear and the drive shaft is coupled to the drive gear. The head is provided in the form of a flat plate with a plurality of holes for accommodating fasteners that couple the head to the distal end of the casing.

Abstract: A pump for use in a filtration process for a deep fryer is disclosed. The pump includes a drive shaft linked to a motor or motor drive shaft. The drive shaft passes through a seal assembly before passing into the pump chamber. The seal includes an outer seal housing that accommodates a lip seal. The lip seal is fabricated from PTFE. A combination oil filtration and supply system for a deep fryer is also disclosed that includes a motor linked to the drive shaft. The drive shaft passes through a supply pump and a filter/return pump. The supply pump includes an inlet in communication with a fresh oil reservoir and an outlet in communication with the filter/return pump. The filter/return pump includes an inlet in each communication with an oil filtration system and an outlet in communication with the outlet of the supply pump and an inlet to an oil distribution network. The oil distribution network includes a plurality of outlets, each in communication with an inlet of a vat.

Abstract: The invention contemplates a rack bushing and a rack and pinion steering assembly for use in a vehicle that includes such a rack bushing. The steering assembly may include a housing having a tubular rack portion with a tubular end, a rack mounted in the tubular rack portion and extending out of the tubular end, and a rack bushing mounted in the rack portion around the rack. The rack bushing includes a generally annular main body portion having a generally cylindrical inner surface centered about the axis and supporting the rack, an outer surface centered about the axis and including a generally cylindrical main surface adapted to engage the tubular end of the housing, and a first end and an opposed second end. The rack bushing may include a plurality of bores extending within the main body axially from the first end a portion of the way toward the second end.

Abstract: An apparatus according to this invention for carrying hydraulic fluid in a power assisted automotive steering system, includes a tube having a tube wall formed with a first port that extends though a thickness of the tube wall. A housing includes a wall formed with a second port extending though a thickness of the housing wall. A retainer is secured to the housing. A fluid transfer line includes a first surface that contacts an outer surface of the tube, is formed with a passage communicating with the first port, is sealed against fluid flow past the first surface, and is secured to an outer surface of the tube. A second surface contacting the retainer is formed with a passage communicating with the second port, is sealed against fluid flow past the second surface, and is secured to the housing by the retainer.

Abstract: A rack and pinion steering gear (10) comprises a housing (12) having an longitudinally extending passage (14). A yoke bore (22) extends perpendicular to the longitudinally extending passage (14) and connects with the longitudinally extending passage (14) within the housing (12). A pinion gear (20) is rotatably mounted in the housing (12). A rack bar (16) extends through the longitudinally extending passage (14) of the housing (12) and is movable relative to the pinion gear (20). The rack bar (16) has teeth in meshing engagement with the teeth (34) of the pinion gear (20). A yoke assembly (36) is located in the yoke bore (22) for at least partially supporting and guiding movement of the rack bar (16) relative to the pinion gear (20). The yoke assembly (36) includes a yoke (38), a yoke plug (42), and an elastomeric spring (40). The yoke (38) is axially spaced from the yoke plug (42) by the elastomeric spring (40).
