Abstract
A valve block mounting arrangement for mounting a valve block directly to the ports of a hydraulic motor. The inventive device includes a main body having a first bore, a second bore and a cartridge bore. The first bore and the second are substantially parallel to one another with the cartridge bore intersecting the parallel bores and designed for removably receiving a control cartridge. A first female coupler and a second female coupler are rotatably positioned within the bores for connecting to a pair of corresponding hydraulic hoses. A first male coupler and a second male coupler are rotatably positioned within the bores opposite of the female couplers for threadably securing to the first port and second port of a rear ported hydraulic motor. The female couplers are preferably connected to the male couplers thereby allowing an individual to apply a tool to the female couplers to rotate the male couplers into the ports of the hydraulic motor. O-rings are positioned about the female couplers and the male couplers for preventing passage of hydraulic fluid about the couplers during operation. A conventional O-ring is positioned about each of the male couplers for reducing the likelihood of leakage during operation. In an alternative embodiment, the female couplers are permanently secured within the bores while the male couplers include an extended portion for allowing a tool to manipulate for rotating the male couplers into the ports of the hydraulic motor. Once installed upon the hydraulic motor, the user may interchange the control cartridge depending upon the type of valve they desire to create. It can be appreciated that one or more of the present inventions can be attached to the female couplers in a stacked configuration.
