摘要： This disclosure relates to street sweepers and interchangeable conveyor modules for use with street sweepers that are interchangeable. A first conveyor module is provided that is mountable to the conveyor support structure of the vehicle wherein the conveyor is configured to transport debris from the broom assembly to the hopper on a continuous belt having paddles. A second conveyor module is also provided that is mountable to the vehicle structure wherein the second conveyor is a squeegee type conveyor. The first conveyor module and the second conveyor module are interchangeable on the street sweeping vehicle. Because the size envelope and attachment points and mechanisms are common, the two modules can be interchanged at will.

摘要： An improved manifold and valve cartridges suitable for high power (over 600 hp) reciprocating pumps for water blast or jet applications are disclosed. In one aspect, the disclosed valve cartridges are compact and mounted axially along a seat member that has a central bore in addition to suction and discharge seats. The seat member can also be provided a plurality of radially arranged bores for allowing suction flow to the pump. A spool valve assembly can be mounted through the seat member bore, and can include a valve spool, a spherical suction valve member, a compression spring, and compression-locked rings. The spool valve can include a closed flanged end that engages with the seat member discharge seat. In operation, the compression spring continuously pushes the spool valve closed flanged end against the discharge seat and pushes the suction valve member against the suction seat to retain a normally closed position.

摘要： A high pressure reciprocating pump (10) for high fluid pressures having a valve cartridge (57) positioned within a manifold block (15) of the pump (10). The valve cartridge (57) has a fixed body (58) with a plurality of equally spaced suction opening (69) extending therethrough. A central bore (70) of the valve cartridge body (58) has a valve assembly (72) mounted therein. Valve assembly (72) include a discharge valve member (74) and a two-piece suction valve member (280) mounted for sliding movement about the outer surface of discharge valve member (74). A spring (84) biased between spring retainer (87) and the two-piece suction valve member (280) continuously urges the valve members (74, 280) toward closed position. On the suction stroke, the two piece suction valve member (280) is opened and fluid through suction openings (69) enters the pump chamber (37). On the discharge stroke, high pressure fluid is discharged through the central bore (77) and lateral slots (79) of open discharge valve member (74) past seat (78). The two-piece suction valve 280 includes a spring seat 282 and a hard sealing member 284.

摘要： A power split and creep drive system for street sweeper or like specialty vehicle having a single engine is disclosed. The system intends to retrofit and convert on-highway truck chassis into specialty vehicles capable of performing work function and moving at creeping speed, such as a street sweeper. It includes a hydraulic work circuit or power-take-off (PTO) port, a planetary gear set, a hydraulic system comprising pumps and motors to drive the working devices and balance the demand between propulsion and work function such as sweeping. The planetary gear set includes an input shaft connecting to a transmission output shaft of the chassis, a first output shaft connecting to a hydraulic machine, and a second output shaft to vehicle propulsion drive shaft.
