The present invention provides a butterfly plate assembly for a bar gun that includes a ball cluster bearing sized and dimensioned to operationally couple the butterfly plates with an interior surface of a handle upon which the ball cluster bearing rests. The welding of the steel balls to the butterfly plates and the need to purchase such precise and intricately small balls is eliminated by using the molded ball bearing clusters that are shaped and dimensioned to fit in the recesses in the sockets of the bar gun handle.

The present invention provides improved retention of O-rings and easier O-ring replacement by using an O-ring retainer in a bar gun. Furthermore, the assembly of the butterfly plates of the bar gun is improved by using molded ball bearing clusters that fit in recesses in the butterfly plates, thus eliminating the welding of the balls to the butterfly plates and the need to purchase such precise and intricately small balls. The O-ring retainer and molded ball bearing cluster are preferably made from bearing quality acetal plastic materials.

A pivot bearing having a first bearing surface of hollow cylindrical design, at least in sections. Guided in the first bearing surface is a second bearing surface of hollow cylindrical design, at least in sections. Rolling bodies are arranged between the bearing surfaces. The pivot bearing also has a cage for guiding the rolling bodies, and a slide block to prevent the cage from slipping. A first grove is formed in the first bearing surface and a second grove is formed in the second bearing surface. The groves are inclined transversely with respect to the running direction of the rolling bodies. The opposite inclination of the groves has the result that, if the spacing between the bearing surfaces is neglected, the grooves intersect. The sliding block is guided between the grooves. The cage has a recess that holds the sliding block permitting cage control.

A cradle bearing comprises a circular arcuate outer race arranged in a circular arcuate recessed part provided in a housing, a plurality of rollers arranged along the inner circumferential surface of the outer race and supporting a swash plate swingably, and a retainer for retaining the interval between the rollers. An engagement member and the end face of the retainer in the circumferential direction are in face-to-face contact with each other.

A roller bearing assembly for a variable displacement hydrostatic unit. The roller bearing has an inner race and an outer race with a cage therebetween that holds a plurality of rollable elements. A link is mounted to the inner and outer race such that the link is able to limit the arcuate movement of the cage element.

In a fulcrum bearing device for a pulley arm, a sleeve is inserted in a shaft hole formed in a boss portion of a pulley arm, washers are fitted on the outer peripheries of small diameter tube portions formed at the respective end portions of the sleeve, and the sleeve is fixed to an engine block by means of a bolt inserted through the sleeve and tightened, so that the pulley arm is pivotally supported. The shaft hole is formed at its respective end portions with seal receiving recesses having large diameters. Each seal member includes a cylindrical portion provided on its outer peripheral portion and press-fitted in the seal receiving recess, and a radial lip extending obliquely inwardly and provided on the inner periphery of the seal member. The distal end portions of the radial lips are kept in elastic contact with the outer diameter surface of the sleeve.

A rocking bearing outer ring (12) includes an arcuate track member (13) having a track surface on its inner diameter surface, and a flange portion (14) projecting radially inward from each widthwise end portion of the track member (13). In addition, when it is assumed that L1 represents a circumferential length of the track member (13) and L2 represents a circumferential length of the flange portion (14), 0.2≦L2 / L1≦8 is satisfied.

A shaft assembly having a first shaft and a second shaft interconnected by a bipot joint is disclosed. The first shaft and the second shaft are disposed in overlapping spaced relationship. The bipot joint includes a pivot block sandwiched between the first shaft and the second shaft. The pivot defines a mounting surface abutting one of the first and second shafts, and a semi-annular surface opposing the mounting surface and abutting the other of the first shaft and the second shaft. A fastener extends through a bore defined by the first shaft, the pivot block and the second shaft to interconnect the first shaft, the pivot block and the second shaft. The fastener includes a spring to bias the first shaft, the pivot block and the second shaft together, thereby de-lashing the bipot joint.

An apparatus for dispensing a beverage, for use with pressurized sources of one or more fluids, includes a handle having one or more valve chambers; a fluid valve in each valve chamber; one or more butterfly plates, each configured to bias one or more of the valve stems of the valves towards a valve-open position when the butterfly plate is pressed, thus opening fluidic communication from each of the fluid sources to a corresponding discharge opening; and a ball bearing cluster which provides one or more pivot points for the butterfly plates. The ball bearing cluster includes a retainer and at least one ball-shaped projection projecting from the retainer. The ball-shaped projection remains in a substantially fixed position and orientation with respect to both the retainer and the handle when one or more of the butterfly plates is pressed. The ball bearing cluster and butterfly plate may be molded.
