摘要: A relief valve assembly (27) for use with first (15) and second (21) conduits, one communicating high pressure. The assembly comprises a housing (29,33) defining first (45) and second (47) ports, and a poppet seat (49). A poppet member (43) and the housing define a spring chamber (55), and a spring (39) is disposed to bias the poppet member toward the seat. The poppet member defines a shuttle cavity (51), a shuttle passage (53) communicating from the cavity to the spring chamber, and the poppet defining a seat (57), and a fluid passage (61P) communicating with the first port, and a seat (59), and a second fluid passage (63) communicating with the second port. A shuttle valve assembly (71,73,75) is provided, whereby the fluid pressure in whichever of the ports is at lower pressure is communicated to the spring chamber and adds to the force of the biasing spring.

摘要: A tool holder having two distinct phases, a first phase in which the tool is held in an interference fit with sufficient mechanical interaction between the two for the tool to be rotated at high speed and perform its intended purpose on a workpiece, and a second phase in which the tool is sufficiently released from the interference fit to be rapidly removed from the holder (as by an automated apparatus).

摘要: A solenoid assembly (23) includes a coil assembly (65) having at least one coil winding (73) and an electronic circuit assembly (67), which is in electrical communication with the coil assembly (65). The electronic circuit assembly (67) has a printed circuit board (79) and at least one electronic component (81), which is surface mounted on the printed circuit board (79). A coating material (85) coats all of the plurality of external surfaces of the surface-mounted electronic component (81). A casing (87) over-molds an outer longitudinal surface (77) of the coil assembly (65) and all of a plurality of external surfaces of the electronic circuit assembly (67).
