Description
A VALVE WHICH COMPRISES A WAY The present invention relates to a and more particularly to a valve for various purposes which is provided with an inner one way passage to be used in hydraulic systems in which pressure must be Hydraulic systems are known which operate presses and the some of which must remain locked under pressure for undetermined periods or To this end speciual valves are such valves must operate under normal conditions and be provided with a locking mechanism which if not allow the back flow of the hydraulic It is thus the object of the present invention to provide a valve of the type referred to for hydraulic systems which is of simple construction including an integral one way valve which prevents the back flow of the hydraulic According to the present invention a valve of a special construction which comprises a housing which is provided with at least one inlet port and one outlet port for the hydraulic within said housing there being provided an inner core member which has at least two crossing bores which can be made to register with bores in said housing to which latter are connected hydraulic fluid one of said bores within said inner core is provided with a s pring urged ball forming a one way The invention will now be described with reference to the annexed drawings in 1 illustrates a valve according to the invention in its normal operating while 2 illustrates the valve in the locked 3 shows a cross section of the inner core of the Turning first to 1 the valve consists of a housing 1 and an inner core member 2 which can be turned about axis said housing is provided with inlet port 4 to which conduit 5 is outlet port 6 to which conduit 7 is Core member 2 is provided with bores 8 and Bore 9 has a greater diameter at one end into which are placed a spring 10 and ball The inner member 2 further comprises a ball and dent 12 which secures the core in its ring seals 13 are provided around core 2 to provide The valve operates in the following The hydraulic fluid normally passes through bore 8 to both thus when pressure is applied the fluid is free to flow from left to right and back into the fluid In order to lock the core 2 is turned through means of a key or the As can be seen in when pressure is the fluid passes through bore 9 pressing ball against spring It is easy to understand that the flow back is not possible as ball 11 blocks the thus the system remains in a locked position practically immobilizing the The system may be re released by turning core 2 into its normal insufficientOCRQuality
Claims (5)
1. A valve for im mobilizing hydraulic systems of a special construction which compr ise s a housing which is pr ovided with at lea st one inlet port and one outlet port for the hydrau lic fluid within said housing there being provided inner core member which has at least two cros sing bore s which can be made to re gister with bore s in said housing to which are connected hydr aulic fluid pipe s, one of said bore s within said inner core is provided with a spring urged ball forming a one way pa ssage.
2. The valve claimed i n claim 1, characterised thereby that the said inner core is movable rotatively within the said housing.
3. The valve claimed in any one of claim s 1 or 2, characterised in that the said movable inner core is de s igned to be so moved with the aid of a key.
4. The valve as claimed in claim 1, characterised thereby that said inner core comprise s a ball and dent.
5. A valve, sub stantially as hereinbefore de s reference to the accompanying drawings.
