Patent number: 8647087Abstract: A hydraulic motor having a cooling system includes a stator, a rotor that rotates and orbits in the stator, a drive link connected to the rotor, and a housing connected with the stator. The housing includes a working fluid inlet port, a working fluid outlet port, a cooling fluid inlet port, and a cooling fluid outlet port. Each port extends through the housing and is configured to connect with a different associated external fluid line. Pressurized fluid enters the working fluid inlet port to rotate and orbit the rotor en route to the working fluid outlet port. The cooling fluid ports are isolated from the working fluid inlet port and the working fluid outlet port within the housing.Type: GrantFiled: July 30, 2012Date of Patent: February 11, 2014Assignee: White Drive Products, Inc.Inventor: Richard Daigre

Patent number: 7909414Abstract: A hydraulic circuit includes a spring applied-pressure released brake, a hydraulic motor, and a control in fluid communication with the brake and the motor. The control is operative between a first position and a second position. When in the first position the brake receives pressure from a first brake pressure source. When in the second position the brake receives pressure from a second pressure source and the motor is short circuited in relation to a motor pressure source. The control can be automatically reset upon pressurization of the hydraulic circuit.Type: GrantFiled: March 10, 2006Date of Patent: March 22, 2011Assignee: White Drive Products, Inc.Inventor: Richard Daigre

Patent number: 7722131Abstract: A control for a hydraulic circuit includes a manifold housing and a movable member disposed in the housing. The manifold housing can include a brake port and a pressure port. The brake port is in fluid communication with an associated spring applied-pressure released brake. The pressure port is in fluid communication with an associated pump. The movable member moves between a first operating position and a second operating position when pressure is not being applied to the pressure port. In the first operating position, the movable member is disposed to allow fluid communication between the associated pump and the associated brake. In the second operating position the movable member is disposed to prohibit fluid communication in a first direction from the associated brake toward upstream the associated pump while allowing fluid communication from upstream the associated pump toward the associated brake in a second direction. The manifold housing can also include first and second motor ports.Type: GrantFiled: February 2, 2006Date of Patent: May 25, 2010Assignee: White Drive Products, Inc.Inventor: Richard Daigre

Patent number: 7513111Abstract: A shock valve assembly for a hydraulic system includes a fluid path extending between a first port and a second port with a shock valve disposed in the fluid path to normally block fluid flow through the fluid path between the first and second ports. The shock valve temporarily opens to permit fluid flow between the first port and a second port through the fluid path when a fluid pressure differential between the ports exceeds a predetermined threshold. Fluid flow occurs in a first direction from the first port to the second port through the fluid path when the shock valve is temporarily opened and fluid pressure in the first port is greater than the second port. Fluid flow occurs in a second, reverse direction through the fluid path from the second port to the first port when the shock valve is temporarily opened and fluid pressure in the second port is greater than the first port.Type: GrantFiled: May 1, 2007Date of Patent: April 7, 2009Assignee: White Drive Products, Inc.Inventor: Richard Daigre
