  • Publication number: 20230175533
    Abstract: A fixed displacement hydraulic pump match flow demand control system that includes a spool valve, a plurality of fixed displacement pumps and a control valve is provided. The spool valve includes a spool. The spool is configured to shuttle within a chamber of a housing based at least in part on a pressure difference between a first end and the second end of the chamber. A fluid flow from each fixed displacement pump of the plurality of fixed displacement pumps is in fluid communication with an associated input port to the spool valve. At least one output port of the spool valve is in fluid communication with a hydraulically operated device and at least one of another output port is in fluid communication with a return. The control valve is configured to adjust the location of the spool in the chamber to regulate fluid flow to the hydraulically operated device.

  • Publication number: 20230011517
    Abstract: A double clutch reverse and active torque management system is provided. A forward variable torque limiting clutch selectively couples torque between a driven sheave of a continuously variable transmission (CVT) and at least one drive axle of a vehicle when the vehicle is traveling in a forward direction. The forward variable torque limiting clutch is set to transmit less torque than can be transmitted through each of the drive sheave and the driven sheave of the CVT. A reverse variable torque limiting clutch selectively couples torque between the driven sheave and the at least one drive axle of the vehicle when the vehicle is traveling in a reverse direction. The reverse variable torque limiting clutch is set to transmit less torque than can be transmitted through each of the drive sheave and driven sheave of the CVT, wherein any slip caused by excessive torque occurs at one of the forward variable torque limiting clutch and the reverse variable torque limiting clutch.

  • Patent number: 10215304
    Abstract: A 3-way high-speed valve including a housing, first and second spools, and an actuator mechanism. The spools are slidably disposed in bores of the housing. The housing further defines an inlet, first and second intermediate ports, and first and second outlets. The inlet is fluidly open to the first bore. The intermediate ports each fluidly connect the first and second bores. The first and second outlets are fluidly open to the second bore. The actuator mechanism articulates the spool bodies to generate differing flow conditions of the valve, including a first flow condition in which the inlet is fluidly connected to the first outlet, and a second flow condition in which the inlet is fluidly connected to the second outlet.
