Abstract: A centering abutment to readily locate the clutch member relative to the side member of the housing of a viscous fluid drive. The side member has an opening for a bearing in which is located an input shaft. Lands and grooves are located on the side and clutch members. When substantial radial clearance exists between the housing and clutch member, problems are encountered in assembling the members. Assembly time is greatly reduced by providing the centering abutment on one of the members for alignment with a trough in the other member. The length of the abutment is greater than the length of the lands on the member and preferably has an angled outer portion for quick alignment.

Abstract: A vehicle engine accessory drive system is disclosed including a hydraulic fan motor (41) and a power steering gear mechanism SG in series flow relationship. The vehicle power steering pump P is the sole source of fluid for the system and has its flow control setting at a flow rate X, which is substantially greater than the flow rate Z required by the power steering gear SG. The motor-valve apparatus includes a valve portion (43), including a bypass valve portion (43), including a bypass valve piston (113) connected in parallel across the fan motor (41), and operable to permit fluid flow from the inlet passage (83) to the outlet passage (91) at a flow rate which is at least a portion of X. The bypass valve piston (113) is biased toward the bypass position by the fluid pressure in the inlet passage (83), and is biased toward the closed position by fluid pressure in a signal chamber (115).

Abstract: A fluid coupling device is disclosed of the type including a valve member actuated by a valve shaft extending through the cover, the position of the valve and valve shaft being controlled by a temperature responsive bimetal coil. The coil has a first end attached to the valve shaft and a second end received within a clip member to prevent circumferential movement of the second end of the coil. The clip member includes wing portions which are generally parallel to the adjacent surface of the cover. After the clip and the bimetal coil are assembled, the coil is permitted to achieve its neutral position in both the radial and circumferential direction, and subsequently, each of the wing portions is attached to the adjacent portion of the cover without causing substantial radial or circumferential movement of the second end of the coil. As a result, the coil is able to withstand extreme vibration conditions, but is not subject to the high hysteresis which normally occurs with a rigid mounting of the coil.

Abstract: This invention relates to an additive dispenser for use in the door of an automatic dishwashing machine. The dispenser includes a dosing chamber and a reservoir and dispenses liquid from the dosing chamber upon closing of the dishwasher door. A scooping chamber is provided on a higher level than the bottom of the reservoir such that upon opening of the door the liquid from the scooping chamber flows into the dosing chamber and is discharged from there upon reclosing of the door.

Abstract: A hydraulic controller for a hydrostatic transmission to control a number of functions of a variable displacement pump or motor of the transmission. A valve includes a spool biased in one direction by a spring and in the opposite direction by fluid pressure in a chamber communicating with the charge pump. A variable orifice communicates the chamber with a drain. The size of the orifice is controlled electrically by a signal representative of swashplate position. Depending upon the pressure of the fluid in the chamber, the valve will directly vary the pressure ported from the charge pump to the standard controller. A needle roller has one end in contact with the end of the spool communicating with the chamber. A high pressure signal is provided via a shuttle valve across the high and low pressure conduits of the transmission to the other end of the needle roller.

Abstract: A fluid coupling device is disclosed of the type including a valve member actuated by a valve shaft extending through the cover, the position of the valve and valve shaft being controlled by a temperature responsive bimetal coil. The coil has a first end attached to the valve shaft and a second end (free end) received within a receiving portion of a clip member. Disposed between the second end of the coil and the receiving portion of the clip member is a resilient elastomeric member having a relatively thin wall. The clip member includes at least one wing portion which is attached to the cover to define an enclosure. The enclosure is configured to engage the elastomeric member which is compressed against the second end portion of the coil on at least two sides. The elastomeric member fills the clearance between the coil and the clip, even if the thickness of the clearance is not uniform, to increase the coefficient of friction, and the total gripping force, between the clip and coil.

Abstract: A vehicle engine accessory drive system is disclosed including a hydraulic fan motor and a power steering gear mechanism in series flow relationship. The vehicle power steering pump is the sole source of fluid for the system and has its flow control setting at a flow rate X, which is substantially greater than the flow rate Z required by the power steering gear. A temperature responsive bypass valve is connected in parallel across the fan motor and the bypass flow and motor outlet f1ow recombine, then flow to a steering gear flow control which communicates a flow rate Z to the steering gear mechanism and all fluid in excess of Z bypasses the steering gear, recombining with the output flow from the steering gear and returning to the pump inlet. This system provides a flow to the fan motor resulting in a fan speed-versus-engine speed similar to a "viscous curve".

Abstract: An electrically operated valve having a mechanically actuated position for valving a fluid port between an open and closed position. A first tubular pole member contained within an electrical coil is movable between a first and second position with respect to a second, stationary, coaxially aligned tubular pole member. A reset spring urges the first pole member toward the first position. An armature, having a valve sealing surface at one end, is movable between first and second positions for alternately closing and opening a fluid port. The first pole member defines an air gap with respect to the second pole member which, during energization of the electrical coil, has associated therewith a magnetic flux with accompanying lines of magnetic force. One end of the armature is spaced closely adjacent to the air gap so that, upon energization of the coil, the magnetic force lifts the armature to the second position, overcoming a second biasing spring which normally maintains the armature in the first position.

Abstract: A crane operating aid comprises a load moment computer and a number of transducers which monitor crane parameters such as boom length, boom angle, and boom reaction forces. The computer then calculates the percentage of load capacity as a function of the crane manufacturer's published load rating tables. The computer is disposed near the crane operator to facilitate interaction between the two and actively solicits crane condition information from him through a prompting scheme which initially poses a series of status requests to the operator. The operator must supply appropriate responses to the status requests prior to operating the crane. The computer also can display any of the input parameters monitored by the transducers. A plurality of alarms of ordered urgency are provided which indicate various overlimit conditions. Both minimum and maximum operator controlled set points are provided.

Abstract: A simplified calibration mechanism is provided for a pressure switch using an adjustable, spring-biased plunger arrangement for controlling the trip force and hence the pressure to which the switch responds. The mechanism includes an especially configured lever pivoted at one end, contacting an especially shaped cam as a follower at its other end and the plunger at its mid portion. First calibration means are provided in the lever's pivoted end to adjust the normal low-high pressure settings of the switch. Second calibration means are provided to isolate the lever and cam from the plunger for effecting a precise setting of the pressure switch at extra-low pressures.
