Abstract: A linear to rotary actuator is disclosed having a fluid pressure operated diaphragm whose linear movement is translated into rotary movement of an output member by a helical coupling therebetween. The coupling comprises a coupling member that is insert molded in the diaphragm so as to extend therethrough and interlock therewith while preventing fluid from passing from one diaphragm side to the other. The coupling member has a combined guide and anti-rotation portion extending from one side of the diaphragm that slidably engages a stationary guide so as to guide linear movement while preventing rotational movement of the coupling member and further has a helix extending from the other side of the diaphragm which in one embodiment slidably engages in a slot directly in the output member whereby linear movement of the diaphragm forces linear non-rotational movement of the coupling member and thereby rotary movement of the output member.

Abstract: A torque strut is pivotally connected about pivot axes at opposite ends thereof between a vehicle and its power train for controlling the pitching of the latter. The torque strut has an elastomeric bushing that is supported for angular movement about one of its pivot axes and has a configuration such as to effect a spring rate acting longitudinally of the strut that varies with angular movement of the bushing. The strut additionally has a drive for automatically angularly moving the bushing to vary the spring rate in response to varying power train operating conditions.

Abstract: A rotary air valve mounted in a case for rotatable movement about an axis to close either one of two adjacent openings has a flexible elastomeric seal that flexibly engages inwardly and outwardly facing curved sealing surfaces on the case to seal the respective openings when the valve closes same. The sealing surfaces have a radius of curvature whose axis is offset from that of the valve so that a predetermined contact pressure is established along the seal at the curved sealing surfaces to tightly seal the openings when the valve is closed but diminishes to zero immediately as the valve is rotated to open either opening to thereafter permit further opening of the valve uninhibited by the seal.

Abstract: A swash plate compressor is disclosed having integral plastic ball and shoe parts with opposing working surfaces of equal area providing the drive between the opposite sides of the swash plate and the inner ends of double-ended pistons that straddle the plate.

Abstract: A hydraulic mount having one variable size orifice member that connects a first chamber to a second chamber with an orifice that decreases in size with increasing pressure differential between the chambers above a prescribed pressure range when the pressure in the first chamber is greater, and another variable size orifice member that connects the second chamber to the first chamber with an orifice that decreases in size with increasing pressure differential between the chambers above the prescribed pressure range when the pressure in the second chamber is greater.

Abstract: A hydraulic-elastomeric mount has a pair of liquid filled chambers formed by elastomeric walls and separated by a rigid partition having an orifice that connects the chambers to effect damping. The partition supports a rigid damping decoupler for free reciprocal movement between oppositely facing rigid sides of the partition so as to effect cyclic volume change in the chambers to eliminate damping under certain conditions. A tapered elastomeric cushion is added to the decoupler to both cushion and cause rocking of same to prevent noise thereby.
